You've got a real talent for drawing. It's pretty sick the way you draw the details.
Only minor point about this drawing is the left foot attached to the rock.
It's just seems weird. Don't get me wrong, the foot looks awesome, but it's just inlogical. If you were to remove that i think it would make a better drawing.
Nonetheless, keep making these drawings and post them. Also maybe you could add your hand made sketches.
When you have enough drawings, you can look for an animator to make you an gallery flash for your artwork perhaps.
