i love that kind of style, very nice n_n
Only comment is that maybe it looks like the circles on the right are out of place. The others bits are like ink splots, but then you have these concentric circles, which kinda makes it look a bit disjointed. Maybe have some blots instead of the circles, and try to tie them in with the character on the left (for example having it look like the origin of these blots is from a splash behind the character).
Looks good man, was hard to find flaw :P
