Now this doesnt have to be a big deal, a doodle on a napkin would count, anyone can join in and if you get busy no worries just do another one another month.
This is not a competition or a critique thing, it's purely for fun and to get the creative juices flowing if you're working on something or would like to start this can get you going if you're in a slump.
I'll suggest for September a sketch of Iron man, you can create your own armour or do an exisitng one, something easy to start with. If we get a better idea though then its open for changing.
Ideas for sketches:
Superman vs Goku
The Boys vs Marvel
Juggernaut vs Blueberries
Skarhead vs Leigh
Xenomorph vs anything!
