Agree with D7K about contrast, saturation, and WB. As far as subject and composition, the first one has blurry stuff in the foreground blocking what I guess is the subject and the second one is bulls-eyed with nothing interesting surrounding it and neither of them is that interesting subject-wise. There are a lot of really good images like what you're attempting here that can be pulled from nature, but developing a sense of what works and what doesn't takes time and study. Learn the rules, break them, and then settle into your own style.
I can tell from your posts you're playing around with shooting and editing and trying everything you can and I totally encourage you to do that. I used to make HDRs that were described by somebody as a "vomit of color" (lol) so it took me a while to be able to imagine what I wanted and create it. And nowadays I don't screw around with really working at it that much. I just shoot birds and landscapes and not much else. It's fun to see people starting down this path. Cheers!
