yeah i think there lights from the marina behind the trees. the one is reflecting in the water.
on inspecting the full size pic
the red on the left is a cars tail light
and the other one is a lampost, below is its refection.
i could clone them out easy enough.
Very nice set!!! I personally love #5, the subject and composition is wonderful! I can't believe you capture this with a 50mm 1.8, guess I should use mine sometimes...lol
