In this tutorial, we're going to use some simple circles and gradients to make a cup of coffee viewed from above. The end result isn't that useful, but the process is interesting nonetheless.
Step 1:
We begin with a nice pastelly-blue gradient. Note that with the gradient, I've put the lighter part in the top right. This is important because we are giving the impression that light is coming from the top right and this is will decide what direction other gradients need to go.
On top of that draw a circle and fill it with white.
