Simple (Hopefully) Faceset Help Request

[Merkaval1]

Hi,   I have what is hopefully going to be a rather simple request.

Basically, what I'm hoping someone can help me with is to recolor the shirt collar on this image to a sort of brick red shade.







And the collar on this image to a medium shade of silver/gray.








I'd do it myself, but I don't have a decent photo editing program, so my only option is to do it pixel by pixel in IDRAW.   :confused:



My next request is probably a little more complicated, and I'm hoping someone can maybe help me with at least part of it ...

I need the man with blue/black hair to have this mark around his eye that's showing:




Obviously it probably won't all fit, so don't take up his whole face with it, try to keep it close to his eye if at all possible.
It doesn't have to be exactly what I drew there either.

I tried doing it myself in Idraw again, but I can't seem to not make it look like crap, seeing as I suck at shading.

And then, a separate set for the same man where he has the mark, and he also has dark circles under his eyes, like he's sick, or hasn't slept in a while.

I know I'm asking a lot with the last two, but I'm hoping someone here can help me out, given my artistic ineptitude.
Unfortunately I can't promise anything except my gratitude and your name in the credits when I release my game.

Thanks for reading, and thanks so much for any help.
