A couple of things come to mind....taking into consideration that I'm a relative newbie to photography....
The images aren't very sharp, especially #5. (Some of the graininess is nice, but not in all cases) Also, while I love the arcitectual subjects, some of the photos are lacking something....shadows, details, focal points...? Also, be careful to watch that the photo is "straight", or that the subject doesn't look like it's falling backwards (#3). #2 is a great subject as well...but I think it would have been better to see the top of the arch?! :O)
Thanks alot, I am some what of an amateur at photography and I agree with alot of what you said. I probably could have payed more attention to focusing and as for sharpness I was using an older 35mm camera so I dont really know if i could have got a sharper picture.
