Woah, this looks great. Love the look of the neon green rail against the grey, really sets it off. With regards to the layout, it definitely looks unique, it's hard to really judge as there haven't been any real world attempts at new, non-arrow style shapings for the 4D coasters, but what's there looks good and seems like it will make use of the 4D functionality quite well.
That fly-to-lie style curve looks weird to say the least... but that's a good weird.
