Love the last one, done very well! #1 and #3 look too saturated but like the composition of both. #2 does not do much for me, the boat cutoff on the left kills the shot I think yet the color saturation of this photo looks real to life.
1 & 3 are both shot with a Singh-Ray Vari-N-Duo Polarizing Variable Neutral Density Filter, thus the high level of color. I see that you are in Elkridge, we really are in each others back yards!
