That's a great portfolio of varied images, nice work
#1 - I love the distortion from super wide lenses so this image works for me, composed nicely and such an intense look of concentration - well captured.
#2 - fantastic angle, exposure is great, colours are nice without being oversaturated.
#3 - Looks like a nice shot, but I think we need to see a bigger version. This type of image relies on fine detail, and a 500 pix version isn't doing it justice.
#4 - Love the subject, so surreal, exposure time works well. My pick of the bunch
#5 - I like the trails, would have been even better with a longer exposure and less of the 'smudging' from the passing cars. Great shot though.
