Honestly this coaster wasn't bad at all. Despite the repetitive layout you created a decent coaster with an intense launch, noice sound effects and heaps of airtime! Overall I did like it - most of my judgement you can tell from the individual scores - and since you're new to the editor here are some tips: Supports Don't use Prefabs - they are not reliable and often unrealistic, so they are on your coaster
The "branch" starts significantly too low
The support branching off of the taller supports is not angled enough
The square box is only used on Intamin coasters with what NoLimits calles it "modern spine". You can change it in the track style settings under spine type. (Intimidator 305 and Skyrush use those spines)
I always recommend to orientate yourself by real pictures of coasters of the same type Trackwork If you find it hard to get a shape right you do nothing wrong if look at pictures from coaster elements of the same type and company. The turnaround you implemented is really strange and imo too slow at the top. To achieve better airtime hill shapes you should definetly use more than just 4 vertices. In fact I saw creators making high quality coasters use a poop ton of vertices. Brakes The last bit of the final brakerun with the catwalks is too abrupt. Instead distribute the deceleration a bit more equally on the entire brakerun.
