I wouldn't know. Haven't been into comics recently. But taking an educated guess I'd say YES, judging by how much digital work there is out there. Especially in the vein of Ashley Wood's graphic look (which I'm sure you can tell I was inspired by when doing the 7yr series).
Jees- loving the movement of the gun- effing fantastic! BTW what brushes do you use, the shading is just so crisp, but smooth at the same time, I still can't figure it out- the effect is stunningly good, I'd love to do something like this but I still can't figure out what you used dammit!
