First off, welcome! I like seeing new members' work. I hope you continue to post here.
Regarding your image, I like the overall composition. I would probably crop out the two trees on the left, because they distract from the three trees that seems to be the main center of interest. This would also crop out the sun, which isn't adding anything to the image.
Before I comment further, I have to point out that I'm looking at the image on an uncalibrated monitor at work, so if this is why it appears this way, I apologize. I would like to see more light in the foreground. It seems that you wanted detail there (and not just a silhouette shot), but it's just too dark to see much. I'm not usually an advocate of HDR, but it may have worked here to get some detail into the tree trunks and the foreground foliage. I do like the motion in the leaves that you captured, and the colors in the sky and the trees.
