Welcome.
I like the angle of the first one but not crazy about all the black on the bottom right of the frame. Trouble is that you can't really crop it out.
The second isn't too bad and I think it works pretty much as is. There may be a little too much dead space on the left. My suggestion to that would be to get a little more of your subjects head in the frame, which would reduce that space on the left. (I wouldn't want to take it out of this pose). There will be some that may suggest to you to shoot this portrait.
