In pic 1 the girl is really good for flash animations, her hip could use a bit of work, and maybe do something with the legs instead of make them points at the end, but the overall look and figure is really good!
In pic 2 I really love the effects you put to it, it's really awesome.
In pic 3 cewt fun and simple, good MS Paint work!
In pic 4, the blending and shading looks REALLY good! Nicely done!!
In pic 5, the ghost is super cewt!! =D I like it, sorta seems like a mario twist
In pic 6, its REALLY good, but I think you could use more practice with eyes
In pic 7, well.. thats my favorite pic, i really like it and would like to see more in that style! =D
Great job and stick around! Be a regular memebr =D That's be super awesome!!! <3333 And keep posting art =D
