I can feel the enthusiasm for what you're doing in your writing here. I know nothing about photography proper, but looking at the photos from an artistic standpoint i can see a lot of things I like. In particular, I can see myself using Photo 3 as a background. I hope someone comes along with good advice, but I can at least provide encouragement - Keep it up!
I also like photo 3. It's the best composition of them all imo. Super_Cyan: The bridge shot is an interesting focal point, but I wouldn't put it square in the center of the composition. I would have it off center. That's just me though. Maybe have it more to the left of the photo with more of that tree on the right taking up the middle. This would give the bridge a sense of having "somewhere to go," and give the shot more space too. I like the water in the first shot. I might have focused more of the composition on it. Though I do really enjoy the green colors you got. Keep the photos coming, I enjoyed looking at them. I bet it was a blast to get out there and create them. Nice work Super_Cyan!
I really got the same feelings coffeesp00ns got in your post. I can certainly see an artistic side to this and I really hope you continue on your path learning and learning. We could see you posting about how you're entered in a photography contest or photography art gallery before we know it!
