Sometimes I just need something arty to do in my spare time. The College art work I do isn't neccessarily fun so I need some suggestions on something fun to do.

I'll attempt anything aslong as it's fun (so drawings, 3d work, pixels, photo manips etc...)

so ofc, best suggestion I will do

Draw Rick Astley, wearing a sombrero getting slapped by a mudkip.
You can do it in cartoony style.

Draw a guy typing on his computer, and you can see the words..."Im bored, what should i draw today?"
