Although its a bit like IDW, i like the idea of another weekly activity.
I'm only doing the occasional sketches (nothing making it to final) right now in the other activities to get myself drawing more regularly. Posting WIP's makes me feel like I am doing something better than nothing.
So because of your strict "if you aren't willing to take the time, then don't bother" guidelines, I won't be taking part in any way at this time.
Good luck with the activity, and maybe when I am more disciplined, I will start participating.
There's a hole... there's a hole... there's a hole in the bottom of the sea.
