Photographers, can I have some constructive feedback?

I’ve always been a big advocate of minimal processing on my photos and have felt that too much post-processing was “cheating”. However, I bit the bullet this weekend and now I’m running a trial of Adobe Lightroom 4.

I’d love to get some feedback on three of my most recent photographs, processed with LR4, posted here: www.nickcomito.me (flowers overlooking ocean, woman looking up, and winterscape)

You may notice that these three photos have a slight difference in tone, quality, and emotion and I’m hoping that those variations make those three photos slightly better than the others in the bunch.

If you have time, I’d love the critique. Thanks!
