I'm shure you find the right balance!
(and I have no experiences in multiplayer leveldesign)It looks very good so far.
Suggestions for the level: put some filling stuff to your level like
- grass/flowers in the border/corner to make it look more real
- and some waste (tins/bananas/...)
- and signs with "Rasen nicht betreten!" (and some footprints nearby)

- or sign "Eisessen verboten!" (and a ice on the floor)) on the alley

Someting funny that makes the player smile.
but all just suggestions...
keep on good work!

[edit] Why wood for the tracks floor? What if its raining? The track would be wavy!
