To me, the color of the pants and the sport coat just don't work well together. However, the shirt and especially the tie are excellent; the top half works well together.
I agree about the trou...just wish I had some that were a few shades lighter.
Panda -> I don't know what it is about your fit that makes it looks so different from Nii's and Orge's, maybe it's the photography, but it doesn't have the pop that the other two combos do, maybe it's because you're sitting too.
Yeah I think it has a lot to do with the darkness of the pants...but I was also trying for a more subdued combo...but the dark grey does seem to throw the look out of balance a bit
