i could do with some ideas for filling gaps in the scenery with my new coaster. its quite big compared to what i normally create so its created some gaps... rather large gaps 

i have already know i have an evacuation rout to put in from the MCBR but other than that, i dont really know. only thing i can think of is buildings and rocks but that is pretty boring. i would post pictures but i want to keep it to myself until it is fully complete

Maybe, and this is a maybe, you could try to put some animals? Seems pretty unrealistic but some parks do put animal exhibits in the same vicinity as a coaster. Sorry. That's the best I could come up with.

I can suggest you a lake, waterfalls and even turning the queue all around the coaster that definitely makes it less boring
