I like the set on the whole, good clear captures, nice colours etc. I think there's something lacking in a lot of the composition of the shots though. Perhaps try a bit of cropping to resolve this and focus the eye more?
Exactly what you've said. In some of them - take #2 there's lots of 'space' in the picture, but the eye is not necessarily drawn to the boarder - particularly with the vibrant wall, so you need to do a little cropping to pull the focus. I'm useless and am not sure how you edit a pic off of here, otherwise I'd happily have a crack for you. Someone will I'm sure.
Strangely enough it's #5 and #6, the no-action shots that do it for me, I think it's the fact that there's also some background activity and therefore the opportunity to interpret more into the scene.... oh and the subject is also quite interesting in a geeky kinda way
Nice colourful shots
With boarding shots, try sticking a wide-ish lens on and getting in close. It can look great if timed well.
Out of those, #3's probably my favourite.
