Brushes on my iPod

First art on my iPod.. after some grueling hours with biochemistry textbook i spend about 30 minutes on this painting. Fully painted on my iPod touch with the app called "Brushes" available on iTunes for $4.99 as usual there's always other way of getting it :-). It is in B&W because i really don't want to mess with colours, i'm not good at colour. :-p

i'll try to sketch other thing on my iPod, if my drawing is improving i will consider for an iPad...
