Wow this track is pretty sweet!
I would like to offer you some ideas & suggestions tho, please take them as constructive critisicm tho as I really appreciate your effort on this track.
* As others have mentioned the textures could use some work
* Ground work IMO could really use some more time spent on it to smooth it out & "carve" it better to make for more fun & a better flow & not so many holes/bumps in the road.
* I got lost quite a few times (even using the map), I think u could really use some arrow signs of some kind.
I really love the idea behind this track & your custom bin models, I would love for you to consider this a BETA version so it can be "fixed up" as this would be a classic if done.
My team (SLO) enjoys BETA testing tracks; maybe you would like to post your track in our forums (SLO General part) @ www.teamslo.com
if you would like us to be BETA testers for it. We enoy giving you our opinions on things & I think it would be good for you to get all the input. If your interested, u will need to upload ya track somewhere as KC's does'nt support direct linking, if you like I can get in touch with someone who can upload it for you. LMK
Oh btw, I have a wav file of the JP theme for ya, searched for it today, also found another cool wav u may wanna add to the start bit somehow, or add to the start of the theme wav somehow if you know how to do wav editing. I can send them to you via email if you like.
Great job man!!
