Freedom Flier

If I was trying to improve the coaster what should I do?

Stop uploading. PRACTICE. Study real coasters and work on the shaping, Your biggest issue lies within the shaping of your elements. If you're not sure, you can ask the other members for advice.

I was uploading it so I can be told how to identify problems.
