I would encourage you to be careful in your use of HDR. I think that you have some nice compositions but may have overcooked the HDR to the point that you lose a more critical audience. A few years ago when HDR was new to everyone, overdone HDR was pretty exciting, but now it is becoming cliche. To people that don't see HDR often, it still looks cool, but do you think your judges will be such people?
This isn't to say that you shouldn't use HDR, actually, I love HDR for bringing out the dynamic range some shots need. I would, however, encourage trying for a more "real" and "believable" result with it.
Having said that, I quite like #3 if it were toned down, I know that I'd be proud of that capture. Contest winner, I don't know, but I like landscapes and I'd like to have taken that one.
The image titled... GRSM -=HDR=- BW... is nice, and even though it is excessive in HDR, I still like it.
And a personal fav (which I don't think anyone mentioned) is #15. I can't explain why, mystery, suspense, story, something... Again, not sure how the "judges" would view it, but I like it.
