I really like how quickly progress on the ride is moving along, it really is starting to look great.
However, the theming, in my opinion is clashing way to much with the rest of X-Sector, and although I have no issues with them going all out on the main feature and how it will interact with The Smiler, I fear there will be way too much yellowness. If you look at Oblivion, (pre fanta) there was barely any orange visible on the buildings or theming, what was included were the orange chevrons around the place, these really did look great, and still do. In my head, the marmaliser should be painted mainly black, but with yellow chevrons.
Also I always notice that X-Sector has a destict 'pipe' design that is present on the Fried Chicken Co, XCell/XPose, Rehydrator, Submission and Enterprise entrances, and the Oblivion queueline. Where are these on the Smiler? No where to be seen it seems. These I think are an essential part of the areas theme and should ideally be included on the station somewhere.
Sorry to rant on, but I fear when the ride is complete we will have a terrible overpowering of yellow, which should be subtle really, just like Oblivion's orange. Also in regards to the Marmaliser, I think simpler is better hear, the whole of X-Sector is fairly plain in style, but it works, whereas like others have said the marmaliser seems to suit Forbidden Valley more.
