good lightning! I'd only use another background. either black or white. The green background distracts a bit imho.
Try a BW-version

else a very nice self-portrait! the two different eye-colors look interessting

Good work,
you look so relaxed in this picture.

Interesting choice of lighting!

Very nice portrait!
Maybe a slight lower exposure would render better tonalities?

I like the portrait, though you could do without the green background texture.
