It's a good start- and I'm no better, mind you, lol!- but I think you need to have more of a "theme" and/or object, in a way. Some pictures are blurred- which is nice for some- but like the bass one, I think it would be better clean cut. I don't know exaclty how many picture you take to get a good one [heh, mine are many and only a few turn out well xp] but sometime times you need to take hundreds to get the perfect one. They kind of look spurr of the moment, in a way. I'd say plan it out some more.
I like the snow one the best. It's pretty neat. Try to get the objective first and then the rest.
Sorry if that didn't make much sense. I'm a bit scatter brained today.
