Poster for Downstroy-Billog gig

I've been contacted to do a DIY style poster for a HC/metal party in Club Terrarossa, featuring Billog from Budapest, Hungary and  local badboys Downstroy;  
here's what's been made in a short timeframe and limited possibilities regarding size/format/colors:

As always, I started with a very detailed, big sketch. Or the opposite. I love these microscopic, simple doodles, it's very fast and easy to show some initial ideas and concepts for the clients.

Then I inked and scanned the final, more detailed drawing in A3 format.

I colored a part of the illustration...

... so we could have something to make a facebook event cover and profile picture.
