Worst volunteer? Please, you have me to contend with for the title!
. Nah, anyone who's even attempting this work and is still here after tackling a project like this is a good person, so enough beating yourself up, OK, or we'll have to have Mr smiley here come visit you
I kid, I kid. Anyway, Wow... The original is so faded out. I think you did a fantastic job on it. At first glance I thought it looked a little splotchy on the clothing, but I believe it's just the light coming through the trees. Overall it looks pretty good and I think it's about as good as it's gonna get. I do see a couple of places that could use a little attention, though. The tree right above the man's head could use a little work. Maybe just lightly using the burn tool on the trunk to even it out a little. Also, above the tree in the leaves there looks to be a red spot that could be taken care of pretty easily. Finally, the very bottom of the image looks to have a little damage. I really don't know what could be done about it, except maybe use the burn tool set on darken to even it out.
