You have some serious potential.
I may not have much to review, but I've been on this site quite awhile, and what you display here is some talent. Your animation isn't as smooth as others', but you have decent art skills and for a beginning flash submitted to Newgrounds, it's better than expected and way better than the average starting flashes. If you want to get better, maybe the flash tutorials on this site will help you, but with time comes experience. Great work, and I hope to see you again one day for winning an award.
