I like the 4th out of all those images the most, mainly because the colours seem more natural and i love polarised images.
No offence but the subject of your hdr attempt wasn't exactly the best, i don't think it works as an image, too cluttered by the tree stick twig branches, sorry man, the gf did a nice job on the sun flare one, although i think it's a bit big for the photo.
