Bubbly Sprite

This is apart of my second series project in my Computer art class. I had to put a self made background with an internet or scanned picture of a real object put into it. My theme is POP! Or SOAD! Which ever name you like!

Now I don't wann boast about my picture, but I must say Im very happy on how I got the bottle to look transparent. I never did something like that before so I feel very accomplished
