wow all three are amazing. first and last are slightly better. not sure about the middle, to me it doesnt look straight, i dunno just something missing
EDIT: Damn I love all you're photos guys, I'm getting better and better at photography at the second, hope my photos ends up like the others I've seen here!
I use photomatix pro 2.5 like you can convert your photos HDR.
its pretty cool. It gives you a quick tutorial how to and what to do to make it HDR, etc.
The fact is its $like 80, but totally worth it in my opinion.
