So after the critique with Jamie today, I got some stuff to work on, and I've ruled a lot of these posters out. I'm going to continue upon elements that are in the last two posters shown here. I'm going to work on better compositions that combine different elements from both, like the lighting from the last one, and the fragmented type in the one above.
Also, I'm working on fixing the color palette, because these looks like indie alt rock band posters, not jazz posters. Fiddle sticks.
