I like the repaint. However the extra hair in front looks a bit awkward, since the color doesn't match exactly. Not sure if it's noticeable if you don't know to look for it, and for all I know it could just be the lighting or the flash. If you can't get a paint color that matches, you might consider just repainting all the hair (both new and old) so it's one consistent color.
Also I'm liking the little burn effect you have not only on the shirt, but on the tie as well.
Can you explain your exact process for staining the white shirt, singing the tie, and getting that dirty effect on your pants?
I'm not all that experienced with modding my figures, so the guidance would be helpful - and these seem like they'd probably be simple enough projects.
Thanks!
