hey dwayne,
don't take it so hard man. Use the criticism to improve your skills. Their comments may be harsh, but... that's just because the photos really are that bad (sorry).
If you want some good advice on how to improve your skills, you're going to have to put more effort into your shots. I'm pretty sure that if the guys here see that you're putting a lot into your photograph and genuinely want to improve, they'll tell you what they like and dislike about your photos and give you some times on how to do it better next time.
I remember when i got my first SLR, i was taking pictures like crazy. most of them were crappy snap shots and i would post them up on here. I specifically remember posting a picture of my car in the automotive thread.
This was the photo:

And i asked, lemme know what you think!
The response was something like:
What do you want us to thing about it? It's a car parked in a garage. It's in focus, but compositionally doesn't do much.
I think it was mannetwork or senna that said it.. i don't remember. I felt kinda embarrassed for posting a shitty photo and wanted to take it down, but instead, i took the criticism and went out to do a proper photo shoot in a good location. The photos turned out soso and most of them were blurry, but i did get some good shots out of it.
but yeah, in the end, thanks guys for giving me a hard time!
