The first one seems a little bit over-saturated to me...case in point, the first two things my eyes were drawn to were the green in the upper right roof and then the foreground (with all of the boxes) rather than the great tractor. I also suggest a bit of a crop (cut out some of the foreground and a little bit of the roof).
Second photo...the foreground immediately gets my attention...not that lovely aged back wall. So this deserves an even greater crop IMHO.
Agreed on the over saturation of the first 1, bring that back just a touch and it'll be great. If you're aiming for "natural" looking HDR, saturation is the first key.. back it off, and back it off again.
#2, it's all about the wall right, so as others said. I'd crop it up to the buckets on the left.
