Advice on RCT coasters

Hi, my name is Paul and I suck at building rollercoasters on my RCT game. So fare I believe me best excitment rating was a 7.5 but I believe I can make it even higher (withought placing props or trees and stuff to raise it a few points). After I am done with my coasters, they are "unbalanced" and look "uncool". I would like to know how all you geniuses make it look balanced and have tons of people wanting to go on your ride. Feel free to put as many advice tips as you want as for I am despret. Thanks.

Do you like your coasters to look realistic or do you just want a high excitement rating? I am not the best creator but I can make some pretty cool looking coasters with pretty high excitements. You just gotta build it like you would like it, but you gotta remember the guests aren't too tolerant.

i need realistic coasters.

Just Practice. It took me a couple of years to nail it down perfectly!

use some real track designs like Medusa, Kraken, Kumba and Hulk, however i perfer steel twister designs.
