Mmm you are having a nice beggining...
well... the problems were the graphics and effects... I've got an idea... look enter to an OekakiBBS: Register, draw something there (dedicate time in it) people will criticize your art and then try practicing with MSPaint, Photoshop and other programs. You can start a DeviantART account too! Ask people how to improvise and stuff.
Well... I'll give you an honest 3 because there are a lot o flashes with this quality, but because you're asking for some good critization, I'll let it survive :) Dedicate time to your work and it will prevail!
