when you're brainstorming ideas:
- think about stuff you like (hobbies, sports, interests, favourite art movements etc). if you do something you don't like you'll probably burn out
- what's your favourite medium: painting, drawing, sculpture (clay, assemblege, carving, etc), difital media, etc. also consider new stuff like film, interactives, etc.
- start off with something smaller. do a few mock-up sketches, canvas boards or something.
- just start doing something. ideas happen.
