i like 3 the best. you may find this works better tho if you use a tripod and a slower shutter speed, that way you will get a silkyness in the water...
#1 is almost impossible to get a good photo there. You kinda have to do it when the sun is on the other side (light up the tree from your side). Or you have to do HDR.
I'd have to agree with the first post, #3 is the best one out of the set. #2 you cut off her hair, don't ever amputate! The first one like schwetty said, almost impossible to make that good unless it's HDR. Also try getting down as low as possible without falling in.
