First things, you need to work on the technical aspect. The ride is to rough. The inversion are too short, the turn are killed by the speed. You need to slow down your ride a little bit. The end was horrible. I'll advice you to brake before it turn to the station. The middle brake zone have to be straight or if you want to slow down your ride, add a trime-brake. Your lift should be straight up also.
I very like the idea of the splash after the first inversion. Use it to brake a bit your ride too.
In fact, due to the technical problem and the speed on your track, this coaster isn't realistic at all. But you have some good element. Without the technical issue, it would be better. Good try.
