First, you should open up an "WIP" Thread with an description and screens of your coaster/project.
Only a video-link to youtube isn't an good advertising in my eyes.
Than you should really improve your video work and learn more how to use the "Flying Camera Editor" in RCT3. With some practice you can create smoother looking camera views than your manuel one.
Your video was really weird on most parts.
Next thing are the "white" cso parts.
The path-covers didn't had an texture or should they be white colored?
But i think that something on the install process was wrong, so they don't had an texture ingame.
Path-covers should be "never" being white, this counts also for an snow/winter area.
If you use CSO's, than you should also use invisible path/queue, too.
Because the ingame stairs looks ugly in the middle of an cso build structure. This counts for the queue-fences/borders, too. With the use of invisible pathes you can avoid all these glitches that you have currently.
The fan/gift/franchise shop should be on the end of an ride, after the exit way and not at the beginning.
I can't say anything about the coaster itself, without an overview from the whole layout.
I would suggest to improve your work before you show it on youtube.
Because youtube can be a b*tch or better the people that are on youtube. With an average/amateur style video you could become more negative comments/dislikes and this can beat you down and the fun to play RCT.
If you post your work here with screens, than the community can give you some tips what is good and what not. And after reworking/improving the bad things, you can allways up it to youtube and become more positive feedback.
Soo long, Cobra
