O comicretard cut em some slack
I agree with him on one thing tho. CONCEPT is very important in this type of aspect advertisement. TITLE is important so is HIERARCHY. The band name is "meh" I would change it up in aspects of placement and all that jazz. As an illustration you did an awesome job I love the art. However for what this is for? its not really mentioning your brothers band, if anything it looks more like a cartoon show rather than a band. I don't think thats wat you want to show the audience. BUT HEY, if it works for you and him, it works. IF I were to pass this by a street or see it in a music store chances are I'd just look at the art and not be really interested in the band. It looks too comical I can't take it seriously. THATS my honest opinion/critique. Take it as it is =) but u definitely have potential! keep working at it :D
