Rollercoasters Upload Help

Hi everyone! If any of you could comment on this post telling me if I uploaded my rollercoasters map wrongly because I have a feeling I did. I dont think I did something right. If I didnt do it right please tell me what to do because Im still sort of a noob at Planet Minecraft. Some help would be appreciated so I could post rollercoasters 2.0 ASAP. I finished another coaster called The Neon Spiral and its basicaly a big spiral that goes up and you turn around and go down the same spiral and its actually pretty cool at the top on far render. Anyways there will be another post about the new things that are going to be in Rollercoasters 2.0. Once again please tell me if I did something in the uploading wrong and how to upload a project correctly. Anyways, cya later! Any help would be appreciated !
