First one is super nice. Second one makes me think you're a wanker.

i like the first one and kinda the third. dont really like any others. the mountain one the mountains need to glow more or something witht he trees being that dark. and the bike one is to dark all around

first and fourth are gorgeous

First and fourth are indeed the tops.

i feel like all of these are underexposed?

i only really like the first and fourth. the rest are kinda just good. not amazing like the first and fourth. the biker one would have been awesome with a flash and the car one if more was in focus i guess, it just seems really soft. don't really know what's going on with the tree one so i am impartial to that one not knowing the story behind why you shot that picture.

hahahhahahahh a wanker!

yeah I just got a remote flash so I plan on going back to those dirt jumps with it.
