The Man with the Yellow Wallpaper

I had my rents bring this old guy back to me last weekend. It's always been one of my favorite pieces ever since I did it back in 2005...that'd make meeeeeeee 16? ish? and just getting started in my serious painting. I  think I had started painting extensively about a year early and this was one of my first pieces that still sticks out as successful even all these years later.

There's obviously things I would probably do differently now. I think the background could have been much more patterned and, given my recent work, would find itself insanely detailed had I done the piece now, but I still like stark separation of the man and the background, mostly through color. The "fuzziness" around his lips and nose are definitely my least favorite parts, but if I remember how my old self worked, control wasn't always my strong suit. I'm torn between adding a couple things and just leaving it as the "original piece."
