Lookin good poutanen, not much criticism to give in terms of exposure/processing etc to be honest but maybe look at composition a little more.
With shots like the one of the grass and moon in the background you might think about moving the moon off centre and across to the left hand of the frame. The slope or the hill provides a bit of a natural leading line that draws the eye to the moon. Normally I'd say to have the main subject on the right side of frame as the brain naturally works its way from left to right but it simply can't work for every shot.
Similarly with the shot of the bird. If you recomposed that one you'd put the bird on the right of frame. Since it's facing to the left, moving it to the right of frame gives the impression that it's got somewhere to go. For any moving subjects (birds, cars, kids, snowboarders, hookers) it's a good idea to leave a little space in front of the subject in the direction of travel/intended travel.
Composition's where it's at mate. Google the rule of thirds, golden spiral (not shower) for some ideas on composition. Don't take them as gospel though, photography's highly subjective and you shouldn't apply "rules" to how you shoot. They're merely a guideline based on how most people perceive space.
Keep it up dude, photography's a great hobby and a good little money maker on the side if you stick with it. I've been travelling all year and have been selling shots to travel magazines, websites etc to supplement funds along the way. I'd love to get over to the US during autumn/fall - the colours look unreal.
I'm back in Aus at the moment and a mate and I chased a sweet storm for a few hours the other week, got a couple of nice shots, the second one is a 17 shot pano at 14mm - the photoshop file was over 4gb once stitched! I think if you click on the pic it'll take you to a better quality version on flickr.
