This is a poster I did for Fantasy Rainbow. Picked a concept and just ran with it - turned out pretty trippy! It has since been showcased on GigPosters.com - a site that archives some of the best gig posters around.
Edit: A quote from the promoter arrived in my inbox this morning “Your design is too good. I put 10 posters up - 9 have been stolen already!” …I’ll take that as a compliment
