Holy crud!! I just looked at your profile, you're only 16! (I am guessing you knew that) You have some talent girl. There is some fantastic stuff in your portfolio. Your PP skills and the thought behind your photos is amazing.
Some nit-picks:
Your horizon is just a hair tilted
The lamp is really crooked
The table isn't centered in the frame
There's a spot on the ceiling (upper right)
Spectacular, Kari! Would only be better if you were seen taking a shot or something maybe. Actually, this setup would be awesome for one of those "multiple me's" photos!
