I think you're really good with textures and coloring and cropping. The only one you've provided with legible text bothers me because the text looks stretched, though I don't know if that's the font... but yeah. XD I was taught to never alter fonts via stretching, good ol' design classes.

I really like the second one from the left on the second row, it's so cute. Also, boobies. Omnomnom.
