This with the pen tool and mouse? or wacom tablet? My wacom is the bomb for free form illustration!

The colors make me feel ill. Abstract art is not my cup o' joe, but I really don't quite know what to make of this. Sorry.

i think the colors make me feel awake, well i love abstract art and for sure i like this one :D. just wondering, why you used red for smoke?

I like the openess of the colors. Very expressionistic use of color, great linework, my only critique would be the hair by the hand has a different line quality to it, more structured than the rest of the drawing. if that part of the drawing was more carefree than the rest it would be perfect. great job!
