My First RollerCoaster

This is my first roller coaster track i have uploaded before but i hope this is good for you awesome Planet MC community.

Please tell me all fails EG:a track piece not working,lava everywhere ect
if you want you can 'remodel' the track make it more intense ect and send it into me and it might be included in the roller coaster maps i will make and ALL credit will go to you guys who makes it :)
and tell me what you like/dislike about the roller coaster oh yeah watch out for creepers on the track ;)
this is creative 1.8.1 so you can re-make the map and re-play it :)
if you want to put this on your server [i highly doubt its that good] just send me a message to ask most likely i will say yes actually i will say yes as long as u try not to take credit for the original track :)
And thanks for downloading :)

and should i make more Roller Coaster tracks tell me in the comments :)
and have a good day/night.
