I tried to be experimental with the light and shadows, but it still looks kinda off. Maybe it's not even the lighting and its the anatomy? I really don't have a good eye for analyzing details...Any veteran artist out there, that can help me with this specific picture? I tried to make it look like the camera is paning up from the desk, but...yeah.

I think the lights and shadow in general are spot on, except for the shadow under the neck, I don't think you need that when there is so much light comming from the back. Also the shadows on the arms and fingers with the different colour also aren't needed because everything is in the shadow already.

If anything the light should he coming from below because the light from outside is mainly hitting the floor inside, then reflecting up, and lighting the lady from below a little bit.

And the "Terminator" eye is too bright, but I'm not sure if that was a stylised choice.

First of all, thank you so very much for answering!

I see...yeah, that makes sense. I didn't think about the reflecting floor though! But if she's leaning with the ellbows on a table, won't the table obstruct the light...?

And don't worry, the Terminator eye was for sure a stylised choice! I wanted her to look intimidating. 

Time to get fixin'! Thank you so very much!
