Here we have an... interesting round.
Winter Wonderland: I frankly don't know why this is here other than to get the competition started, next!
Gun Metal: Nothing particularly remarkable about this entry, the layout isn't particularly realistic or interesting. Not much time was really put into scenery work or landscaping either from the looks of it - granted this appears to be a RCT1 coaster, but that's hardly an excuse. Take a look at other entries from the game you've decided to work in and take inspiration from them to improve.
Talon: Not much to comment on here, it's complete and looks fantastic. The custom chairswing was a nice addition as well, the Egyptian rubble may have been a little overused as rocks though. (Talon also claimed my vote)
Splash Battle: I think what has consistantly peeved me the most about nearly all of the RCT3 entries we've seen in the last year is that all of them show potential and show that you know what you're doing with the game, yet for some inexplicable reason decisions are made while the project is in development that tear what you're trying to accomplish down (get ready as this may turn into a tiny 'rant').
- Foliage: In the background of the screenshots - and POV - I can clearly see that you know what you're doing with custom foliage in the game and that you can make it look rather good. What boggles my mind is that you chose to avoid using any of it near the ride itself and rather chose to use vanilla cacti among other objects (such as dead trees). Why? For the most part vanilla foliage isn't bad, but when you put it in the same shot as custom foliage that has better draw distance, higher poly models, and more detailed textures they just look bad.
- Scenery: For something labeled as being 'very custom scenery heavy' it sure doesn't look like you've made use of much. Sure, there's the backdrop foliage, the stationhouse, paths, the ride, and one odd building or two, but the majority of what is seen around the ride in the POV are all vanilla assets. I understand that there aren't animatronics for Western themed things on CS Depot (mostly because people don't make them), but that doesnt' mean mixing vanilla and CS is something necessary here. As stated with the foliage, the two styles simply do not mix well in RCT3. Some sets you should look into if you plan on making more Western themed rides include (but are not limited to):

Also, in the future consider using more flowing styles of path covers and curbs. The wooden style that you've employed here works really well with stations but generally doesn't look the best elsewhere because it adheres perfectly to the vanilla grid and cannot form more angular or free-flowing paths.
This is certainly not bad, but there is still room for improvement in a lot of areas. Picking a different ride type next time will also allow you more freedom to experiment with terraforming and painting as choosing a water ride really forces you to stick it in a level body of water.
