if you haven't heard of it, Tim Miner runs a great website called 5 Minute Marvels where he and his daughters Grace and Cate draw various characters in five minutes, it's super fun and you should check it out if you haven't. they're very prolific and their renditions are always great. sometimes they invite other artists to join in, a while back i did Domino of X-Force with them and i had a great time, and Tim invited me back again and this time we did Shadoweyes!
and then mine!
