#1 doesn't do anything for me but mostly because light trails are not my cup of tea.
#2 I like what I see very much, but it looks like a drawing more than a photo.
#3 I like how you captured the subject a lot, but the background is too much in focus for my taste so it's a bit distracting. Maybe a tad less DOF the next time you run into this insect? Also, I'd rather have the subject not so close to the centre of the image.
#4 is probably the one I like the most in this lot. I know it's just me, but I would have composed it differently: there's maybe too much water to the right of the image and not enough dog tail to the left (unless, of course, this particular dog was tailless).
#5 What am I looking at? (Seems a bit overexposed.)
