In the first pose be careful with the flash, (I'm assuming you used a flash due to the outline behind the head). Maybe you should use a diffuser on the flash or a reflector. Or if the camera has a flash adjustment, experiment with it. I agree with the comments about isolation and the lines.

Second pose-move away from the bush, looks like it is growning out of his head. Shallow dept of field would help. A little close to the wind vain and shot from the waist up. Reflector on the shadow side to open up the shadows.

Third pose-agree with previous comments.

I thought this was a discussion blog where I could get some critique of my images. I posted images on the 30th and I do not have any.

These were taken with my Nikon D90 with the 18-105 zoom lens.

I just joined. I worked as a photographer for about 7 years doing church directories, glamour, and fundraisers. But, that was with film. I am starting out on my own doing the same thing, but digitally. I need all the help I can get I know. I have a lot to learn. From what I have seen so far on this site, I am sure I will be able improve the quality of my images greatly.
