Alright.
The overall idea is good, but the character's body is just bad. The right hand grip looks wierd, angle of the torso doesnt match the angle of the... ass. The stomach area looks like its about to explode, and the back looks like the skin is too tight, shrinking the overall back area. Also, if you could use your own drawings of fire and/or lightning, thatd look better.
Might I suggest you study the makeup of a body, or the anatomy of it, or go to the extent of looking at what you look like when making that pose in a mirror or something. I do that alot.
The monster looks alright, but the lines are broken in a few places(unless theyre supposed to be), and the tentacles look to be bigger on the tip than further down.
Also, if you look at the battleaxe, it would seem that the side that should hit the monster is smaller than the other side. It would seem that the larger, chipped side would hit the monster, as it would in most cases. Just flip the axe around, or make the sides equal.
An "A" for effort, I would give. A 5 in stars, I have given.
