As self-portraits go I love it.
So much is contained in such a small expression.
Im no professional but I have shot for several amatuer actors wanting profile shots, and this look is what I normally go for and often fail to achieve.
Good work especially considering its a self portrait.
Now Crit time :
A bit more fill light on the left (our left) would be nice,
I presume this is taken with F1.4? Or at least F1.8?
Anyway, focus point seems to be about 3cm infront, and 2 cm to our left of the tip of your nose.
Apart from that minor critisisim job well done!
