Project Finding "Nory" (Dory + Nemo) build/custom

I like it, you'll also find the 'gritty' nature of that spray will help with traction on climbs, its one of the recommended ways of helping Advance trains climb non-advance gradients

Still think you need some orange corel though - maybe if you got some pipe cleaners, painted or dyed them flourescent orange, then bent them into 'trees/coral' to go alongside the track and/or made a loop over the track (like a very narrow tunnel) that would look pretty cool
