Always happy to see you posting photos Pete.
The one thing that jumped out at me (in a negative way), is in the first one. The edge of the dark tree behind him, lines up with the side of his head. With his dark hair, there is a lack of separation (on my monitor at least) and it gives a bit of an awkward look/feel. If the print has better separation there, it's probably not something to be concerned about.
If I had to pick something in the second one, to nitpick, it would be that I'm finding it hard to tell what/where he's looking at. The position of his eyes, makes it look like he's looking at the camera, but something gives me the feeling that he's looking, ever so slightly, of to our right. I'd rather it be clearly one or the other.
