Don't like the first one, but it could be improved if you cropped out the left column, or you shot it in portrait and zoomed in a bit. I don't even know where to look.
The 2nd photo is okay, but I wish you zoomed in a tiny bit. Your position within the frame is ok, but I want to see you slightly clearer. In my opinion, the expression on your face is important to see, but I guess I can understand why you want the person to be tiny in the image. I like you tiny, but I still wish you were a bit larger. It does look good though. I guess there's a lot of things you could have done when shooting this image, and what you did is something many other people may prefer.
