I've been designing posters for shows, movies, events, and everything else under the sun since I was 15. I typically don't get much input from the client (although any and all input is welcome and appreciated) and so I just go with whatever I think would be best for the situation. I like to think I shine under pressure and so the challenge of creating something out of thin air (usually on short notice) or creating something within the constraints of a client's needs and resources is definitely the most rewarding part of what I do.
These are some of my favorite posters I've made over the years.
