Not bad. Your work on paper outclasses your work with sprites, I believe. However, I believe your scan quality is lacking in your physical art; much too grainy, and lined paper is really a big no-no.
Not about to judge someone's spritework, since I don't sprite myself. I do dig the glitch Raikou, though. Seems believable as an in-game error.
Clean up your scans. Also, take a little more time with your work, and your abilities will start to sparkle a little more.
(as a side note, curse you, serebiiforums. every time i think i've escaped, i find myself crawling back)
