It's rather difficult to make any meaningful critque with these examples cfb as they are rather small, but I'll do my best.
I'm just wondering if these were taken with a digital or film camera, I'm thinking film, and I seem to remember you used scan the photos into you computer. Is that what you have done here?
I'm going to ignore the bottom three photos, they look like reference snap shots and have nothing to please my eyes.
Generally the rest suffer from poor exposure either over or under. The composition in #4 and #6 is good and both are worth working on. The rest have poor composition and lighting.
Here is a quick example of one of the photos with the lighting a bit more balanced.
Having said all that, I have the feeling that you are using your photography for more than just recording images faithfully. You have a very artistic eye that is fond of the abstract from what I can tell and I think this shows in your work.
For instance photo #7 seems to have an overlay of the film as in a contact sheet. This can sometimes be very effective for a "grungy" or half finished studio feel, but here it looks a bit of a mess, there is nothing there really to see.
I am not a very good photographer cfb, but since I got myself a digital camera I have taken thousands of photos. Each day I go out I can take a hundred photos. Out of that I am delighted if one of them is good. Do that for a couple of years and you tend to teach yourself what makes a good photo and what does not.
Very often I will find myself in a place that I think will look great in a photograph only to go home load it up in the computer and be dissappointed. Some things just look great and it is very hard if not impossible to capture that in a shot.
Keep on working on your photography, I do like a lot of your stuff, I would just try be a little more selective in what I published or posted.
