the twist at the top of the first pick looks to tight. the entrance to the second twist does not look right but the exit looks ok. that is about all i can tell from the first pic. in the second the loop does not look big enough and/or shaped quite right. hard to tell from the pic
If you're going for realism, vekoma wouldn't put LIMs when the track is upside down, they would put it when ever the riders are laying on there back. But still you don't have to do that but it would seem fun to have a launch while you're flying.
