Portrait in sepia tone

Hello everyone!
Although I'm pretty bad at portraits, but this one, for some reason, held my interest. Sepia tone makes it look a bit more interesting I think.
This image was cropped, resized, sharpened and in the last, sepia was applied.
Following gear was used:
Nikon D70S, Nikkor 50mm 1.8, Nikon Speedlight SB-800
I would appreciate C&C.
Focal Length = 50 mm
Aperture = f/3.2
Shutter Speed = 1/40 sec.
ISO Rating = 200
