Barbucci and Allaze collaboration

this drawing is made during japan-expo and i was so lucky to get his permission to color on this pic barbucci is a very cool artist that i ever meet :) i give him my site about my art stuff and i of course showed one of my art stuff and he like it very much and in the same time, he laugh with joy to see that i got some original idea about character for about this collab, i was too affraid to show out this one because i'm not sure if it's ok to show it well, now you're nejoying to see how i color on this pic

ps : i tried wacom cintiq during japan-expo, it's really amazing as tablet, i really want to get one but it's TOO much expensive... T_T
