Here's my contribution. Sketched it during work, lettered quick at home. It sort of evolved as I went along. Didn't even really start out as Indy but sort of just became him..kinda.
Lots of cool Indy's up here.
HellBoyOne- Mignolaish indeed. Nice. Your second one is even nicer.
SPX- Indy animated. I like it.
EM- Struzen inspired. I like it a lot. Captured the likeness spot on. But then you always seem to.
Daniel- only disappointed there isn't more of Indy on the book cover. Captured the old paperback look very well.
Jeff West- Top Notch!! Love the cartoony look and yet you show off your portrait skills as well.
Creamdog- another cool animated Indy.
I feel inadequate posting my pen sketches here..got to do some more "finished" stuff.
