Decent
Okay,
This was a flash with that deserves a "decent" remark.
You obviously master the use of gradients, and the pencil tool. [Very realistic characters, big plus]
You're using great techinques, keep them up, and really, look around, try to steal some other techinques, etc.
But watch out: Your anatomy isn't top noch from time to time [quite horrible actually] and being a "super hero" flash, this is something really important.
Try to keep even the feet as a seperate symbol.
Also, your perspectives seems to be off alot. Try sketching something on paper [use a center point, and draw all outlines towards mentioned point] and then draw it out in Flash.
I don't know what your drawing tools are (mouse-tablet) but I don't think it'd be so hard for paper to virtual porting.
If using mouse, this works great, if tablet, just sketch in flash.
And the gradients, don't exagerate.
