Are you taking turns with the weekly contests now or are there daily weekly contests? XD
This is actually a great idea for a contest given how challenging it is to get people to branch into shading to begin with (the number of times over the years I've had to cajole people to work at it because they don't want to ruin their nice lines XD).
hahaha no, @kristyglas on her last post asked if someone wanted to make another weekly contest :3 so i volunteered xD and yup that's the idea! i'm no expert either but i think it's a nice way to motivate people to leave their comfort zone and it's also a very fun one, i'm always trying different things xD
