Not bad at all! My only critique is the lower left corner is a little dark as a result of only using 1 light....use two!
This, I know, but am limited on space in my house and didn't feel like busting out a 2nd light. Plus, since the 2nd light would be a fill anyway, I'd still probably get the gradient going against the wall anyway unless I came 6-10' away and used 2 lights to light the wall evenly...
Also, neat looking self portrait!
