Looks to be unfinished. Textures on the man and the rocks are too stark. They need more blending and the rocks need more... rockiness. They look like folds of cloth. Give them more of a grainyness.
The woman looks a bit mannish but that does admittedly fit in with the art of the period (Not to sound like some historically accurate prick or anything).
One thing that really jumps out at me is the red cloth. It looks f'in wicked. Angular yet still soft. And the color just jumps. cool shit.
Also watch her elbow... just an awkwardly jutting angle there.
