Step 1 - Background PreparationI’m working with a 
580px wide and 
700px height at 
72ppi document.
For a print quality file, 150-300ppi is just great, but still.. it depends on your printer’s desired file size.
Use the 
Gradient tool (G) for the next step and set it up to 
Radial Gradient, as shown in the image below..

Apply then the 
#eef5fd for your 
Foreground and 
#84b2ed for your 
Background.
 Step 2 - Rectangle Tool Implementation
Step 2 - Rectangle Tool Implementation
Now... on 
two separate layers, create 
two main shapes using 
Rectangle tool (U) you've set up earlier (see the image above) and don't forget to name each.. 
(1) Main, the body of the bottle shape layer and 
(2) Cap, for the cap or head of the bottle.

My both shapes above created by repositioning the upper side of the 
Main layer as well as the 
Cap layer by 
Transforming the 
Perspective of each shapes wider.
 Step 3 - Coloring (Fill or Adjustment Layer)
Step 3 - Coloring (Fill or Adjustment Layer)Now we're gonna add the 
color and also the 
shadings for the main shapes we made, both of 'em. 
First we should activate your 
Main shape or 
Cup shape by clicking on their layer (you just pick one of 'em, lol)... (I just couldn't think of anythin' funnier to put there.. Sorry).
After that, click the 
Create New Fill or Adjustment layer button at the bottom of your 
Palette layer. We will add a 
gradient color to cover the shape. Choose 
Gradient.. there is little pop up windows come up, set like the image below..

The color combination I put on the box is the color I used on the Step 1. It's all arranged with that way (...of life, again I just couldn't think of anythin' funnier to put there..) just because.. we wanna make the cylindrical illusion in that shape.
Rasterize that 
Gradient fill layer by 
Right+Clicking on its layer, than hit 
Rasterize Layer. Hold on..! Why you should do that? It's because you will 
rotate the 
Gradient Fill layer and 
fix it with the 
Cup (The Cup of the bottle). Just because I'm so lazy on adding it by way a selection or something like that (or just because I’m just that kind of guy).. so I lose my mind with this?!?! Lmao! You should 
Rasterize it first so you can edit just like what you want :p (Did you notice.. how many 
Rasterize words in this paragraph???)
OK..(still.. no better joke)  Take a breath for a moment guys...!
While you're done preparing your 
hot delicious coffee with a 
djisamsoe or something, sit back and complete your work flow... Now.. I'll give this two alternative in coloring. First.. You can use your 
Brush tool (B) set to a size of about 
90px, color the 
Main shape (the bottle layer) you made with this two color 
#252525 and
 #FFFFFF, and change the 
Blend mode into 
Hard Light, and 
turn the 
Fill down into about 
37%..
Or you can add a 
New Gradient Layer above the 
Main layer to cover up the bottle just like I did with the 
Cup.. Here I use the 
second (just because that's the point.. that what I', talking about) to apply the color (of course with 
the same sets as you use for the 
Brush's).

Let's get back to our 
Cup.. we have something to do with the 
gap between the 
Cup and the 
Main bottle... First, 
Ctrl+click your 
Cup thumbnail to invoke the selection of it. While the selection is active, 
click the 
gradient layer above the 
Cup layer, we're gonna add another 
Gradient Layer above it. Done? Ok, don't go anywhere, you should do 
click Create New Fill or Adjustment layer on the bottom of your 
palette layer, then choose 
Gradient! Fill it with 
#002350 and
 transparent, 
Style = 
Linear, 
Angle = -
90. Leave the 
Scale 100% and 
Check the 
Align with Layer.

Then your product will become like this...

That's not good, is it?!?! Who's the one that agree with me... it's not good enuf! Raise your hands. lol!!! Let me tell you this.. you'll need this to fix the prob. 

Click 
Ctrl+T to invoke the 
Transform tool.. 
Drag your bottom 
Gradient Fill (you've created above the 
light blue gradient) just like I show you here.. watch this carefully!!!

Put your 
Cursor between 
Gradient Fill1 and 
Gradient Fill 3, hold it there, press 
Alt.. than you'll see the icon of 
people wearing headset, lol (shit.. I dunno what to say doods!!!) D'ya know what I mean?!?!
That's what we called Clipping Mask fellas.. Take it easy! If you see that damn ghost, Hit your cursor (click it)! 
Your image would look like this.. If it doesn't work..?!?!? Repeat until you get that, lmao!
