Nice lines/angles. I think it could use a bit more contrast, though. There seems to be a lack of shadow that puts the whole image into a very narrow tonal range.
I agree with the last poster--try more contrast. Have you played around with Curves in Photoshop? You may also want to try different types of cropping. But nice lines and angles.
i think the post-processing on the metal bars is just right, i don't think it needs any more contrast. not really a fan of the composition though, but that's just me.
Thanks for your comments, guys and gals. This is the best post-processing job I could do (needless to say, my PP skills are very limited). I'm more than willing to send the original RAW file to whoever wants to take a stab at it. Just let me know.
