I love the Prowler, so here's my attempt, using the same recipe as most others that I have seen.
Not much to tell... I cut the claws, sculpted the belt and those arm- and leg-things
I sculpted the part of the cape at the front, and at the back it merges with fabric so that it can easily be folded and he can sit in a cool pose on the wall.
At first I thought that my drybrush of lavender color was a bit bright, so I tried it with a more colorful color and it looked horrible, making me quickly go back to this, which is actually pretty close to the reference picture, so I think it's pretty good.
It overall isn't the best Prowler custom I've seen, but some aspects of it actually is, so I'm happy. Hope you guys think it's cool.
