Hey! I drew that same picture! It's kinda hard to see the face, which I don't like anyway, it didn't come out very good, but here's mine... not as "soft" as yours, and on lined paper. I also spent about the same amount of time.
Here's one that's not really Indiana Jones... but I spent a lot of time on it, and this one isn't on lined paper! This is what happens after you go through drawing bad faces for a long time... you start to draw like this!!! This one took me about a day and a half to do...
By the way... I don't mean to hijack your thread or anything, if that happens. Just thought I'd show you my version of that picture.
