I've helped some friends with book covers, retouched pictures for companies and friends who do modelling.
I've done banner and signature designing, as well as complete frame by frame editing of short films for a a more finished look.
I am terrible at vector drawing, but I'd love to master it. Freehand drawing is great, but I just am not that good at it. I never find the time or make the time to really master a skill like that. So it stays bad too.
