Very good round! Thoughts...
Friday the 13th: very funny comment in your coaster desc lol (Failed roller coaster architect Terry W. Inferno). good scenery and an equally funny background. A solid RCT2 coaster although without a video or having the supports invisible it was a bit difficult to determine the layout. This coaster has potential to win but as Chima said, unlucky entry timing.
Iron Patriot: A very smooth hyper coaster, with a rather unique turnaround. Fitting colors for the theme, and the support work was decent. The biggest thing this coaster is lacking is scenery, there were not really enough hills or trees, the ground was pretty flat and barren.
Basilisk: A pretty solid RCT3 coaster although there were some faults. A bit of terrain painting was used but aside from that the ground was pretty bare of smaller shrubbery. The castle lacked details, it was just the towers straight from the set, not much else added. The first half of the ride was pretty well done, but not so much the 2nd half. It was almost like a night and day difference scenery wise between the first and second half. There is also a tree at 1:46 that will injure riders on the left half of the ride.
Lyndvior: A very nice invert with great scenery, my only real problem is that the ride is paced a bit too fast, especially through those inversions near the beginning. I also dislike the blur effect but that is just personal preference
Vote goes to either Friday the 13th or Lyndvior.
