Portrait IV

What to do on such a boring afternoon? just practising a bit portraits and  the ilumination (it took me about 4h, no ref.)

I think i like more this version, even though it's less defined.

The final version....i'm not quite satisfied with the result, there is something not working but i can't figure it out, any suggestion?¿

Color key I

Due to the lack of landscapes in my portfolio i decided to draw a bunch of them, this one is just a quick sketch to check the colors and lighting.
