hmmm... just my opinions, but...
1 is way oversaturated IMO. I assume you did this intentionally, but it's pretty extreme. The vignette is distracting, but that's a preference thing. I generally don't like the effect. I think if you had put the horizon not quite in absolute dead center it might have made the shot a little more interesting. Pretty clouds, though.
2 is just a hair dark I think, otherwise fine, though not terribly interesting for me. Of course, I also am not a big fan of flower shots. They bore me silly. Again, preference thing.
