Okay. I just tested. It was a fair attempt at something outside of the box. I have many suggestions though. Here they are.
* Replace the concrete and wood material footsteps with skating sounds
* Replace the metal footsteps with a grinding sound
* MAke different weapons with different pulling out animations so that if you press a certian button, it does a trick. ie. press 4 does kick flip
*Try to keep the framerate up and not let the player on grass
I could also help you with some of these things although Im sooo busy playing videogames and playing guitar(summer break

)
I also need practice modeling and texturing so i could help you with the ramps and other stuff
Peace out,
