I've finally got a theory on doing posters.
For bands that nobody has heard of, such as these, mine included, I'll go crazy on the illustration, and have the bands' names and info be a minor part, since their name won't attract attention, the illustration might.
Bigger name bands, whenever it is that I get to DO some posters for them, will have bigger text, less elaborate drawing. I'll get more 'designy' for them. My 'Arrivals' poster is a good example... of something.
