A lot of people run after the peak season, though I personally like going out at the end of autumn when the crowds have died and the onslaught of colour is a little less overpowering. Sometimes less is more.
I like them all. I think #1 could be improved through additional cropping.. I feel there is too much canvas in the right 1/3 that really adds nothing to the image. In doing this, also getting rid of about 1/4 of the bottom would really improve this I think. Other than that.. #2 is incredible. Great eye. #4 is my second fav. Thanks for sharing these! -Mike
