Tamron 17-50mm f/2.8 XR Di II LD Aspherical IF SP AF

I would like to start off by saying that I am very new to SLR photography. So far, I have just read a couple of books, but no real experience.

I purchased this lens as a replacement for the kit lens that came with Canon XTi. I never actually tried the kit lens.

I am a little concerned that these lens are not as sharp as I was expecting. I read some reviews ( here and in amazon), that some copies of this lens are bad, while other copies are excellent. I am worried that my copy might be bad, so I need some help from an expert. I would really appreciate it, if someone could take a quick look at my sample photos and let me know if this is the quality that is expected from this lens.
My photos are here: http://picasaweb.google.com/slice4e/Tamron175028TestImages?authkey=m7RBlm4HL2Y

When you view those photos, there is an option to download the full image as well.

Thanks a lot in advance for the help.
Anyway, those photos may be useful for people trying to decide if they want to purchase the lens or not. I have tried to include several different lighting situations, etc..
