I am also an art major.  Fine art originally (oil on canvas mostly) and then went into mostly photoshop stuff.  Went to Carnegie Mellon and then the Maryland Institute.  Some nice stuff you got there.  Keep working on it!  If a may give a bit of advice, try not to use to much brown on your photoshop paintings.  I am guessing that one is a self portrait.  There are so many more colors on your face than just brown, light brown, and white.  There are all sorts of blues and greens, some yellows and reds.  Just don't get stuck thinking well skin is a tannish color, because it really isn't. 

For the vodka one, you should make the top background taller.  The background sort of mushes the bottle making it seem small.  When advertising something you want to make it look big and exciting.  A towering bottle, better than all the rest.

And here is one of mine.  My version of an old meme.  Feel free to crit.
