Every once in a while I'll draw something based on sketch challenges I find online, just to mix things up. I just found out about a site that has a weekly challenge, Illustration Friday. It's nice that it's a regular thing and seems to have a lot of participants. I'm dipping my toes in the water with this week's challenge 'talisman'.
I'm taking the approach of working with the first image that pops in my head based on the theme and then knocking something simple out. Just keep it quick, fun and hopefully better with each passing week.
