I recently completed work on my first app from scratch. Featuring a thousand questions covering all genres of metal and alternative music all the way from AC/DC to Anthrax to Cattle Decapitation to Asking Alexandria. Metal Approved was envisaged as the ultimate metal pub quiz. With no time limits or special weapons it's been designed as a casual game you can pick up and tackle when you want.
For the artwork itself i wanted to do something cartoony and not too serious but not too cutesy. Obviously it had to be black with studs and skulls. Here's some initial concept sketches, artwork and finished screenshots.
