Disclaimer: Don't be discouraged by the low rating from creating coasters - And if this is one your first coasters then holy shit, that's damn good for someone who just starts out. I am still forced to rate it objectively though, so here we go.

Coaster

One thing I was surprised about was how smooth this was. I really only noticed one bump however the coaster also felt like it was going in slow motion. That means all the elements are too drawn out (except for the final two bunnyhops - these are almost perfect for some reason). B&Ms are in fact more graceful than others like Intamins but you exaggerated a lot. As for the lift-hill, the pull-out started too early, maybe try aiming for a kind of circular shape, then it should work out better. The drop is also too steep, looking at reference pictures is one of the best ways to get at least the rough shapings correct. Same goes for the supports: I highly recommend not using prefabs because the angle between the vertical and sloped beam is far too low which can only make a coaster look unstable and the custom ones you did actually build don't really make sense either. So again - reference pictures :)

Scenery/Theming

I like the way the coaster uses the valleys of the bumpy terrain to dive into, however, the terrain is quite arbitrary. I don't mind some subtle hilly bits here and there but you have to figure to what degree it feels realistic. So looking at it I think the scenery is fine and neither particularly realistic nor unrealistic.

Overall a bad coaster comparing it to the full list of creations, but still, for beginners, I think this is a very good ride. Keep training I am sure you can make at least good rides within a few months. :)
