Nice! I like the 2nd and 3rd ones best. I shoot almost everything with auto bracketing (-2, 0, +2) because I like HDR so much! Sometimes I blast the HDR effect to really liven things up, and other times I use it to simply "correct" the shots and bring out the color. Depends on my mood. Keep playing with it!
BTW...Have you tried the trial veresion of Dynamic Photo HDR? I use it and l've it! ...especially since I don't use PhotoShop and my editor at the moment is an OLD version of Paint Shop Pro. You can download it from here:
Dynamic Photo HDR.
