I am not an HDR guy myself, but I do love tastefully done HDR images. The colors are very rich in all and photography, despite the processing technique is subjective.
Composition is fair, colors are vivid, perhaps a little too much on the blue in 1 & 2 on the water - just a tad less and would suit. Skies are good in 1 & 2, but overdone in #3, where the water is wonderful.
