A few things come to mind. In the first one, the building in the background is very distracting. A slight change in position could have removed it from the frame. I also think it would have worked better were the model angled a bit instead of straight on. Before you trip the shutter, always take one last look around the frame for things that might be distracting. Better to change it then than have to re-shoot later!
In the second one, we are still dealing with a distracting background. I think a little less turn on this one and maybe having him do something with his left arm to generate some interest. The pose looks very stiff to me.
Both of these images could have benefited from a weak (- 2 stop) fill. There are some dark shadows around his eyes, no catchlights in the first one and only barely perceptable ones in the second. If you were shooting digitial, which I am assuming you were, a change in white balance to cloudy would have removed the too cool cast to the images. I am assuming you were going for a desaturated look in these images, because the color is very lowly saturated.
I am sure digital has it's place, and hopefully one day I will find it. :-)
