Self portrait (Practising)

Sorry about the uninteresting and somewhat distracting background!
I'd just like some tips and critique on the colour, how i've lit myself, how it has been edited etc. What flaws there are, what you think work if anyone can.
Much thanks to anyone

Note: Tiny room, the light behind me couldn't go very far side to side! I need to get some time to go outside and practise as well as maybe get someone to model
