I downloaded everything and checked it all out.
Lazers cool. The element is really, really neat. I took the liberty of attempting to fix things up, but I think it'd be best if you ran this idea through Newton.
Juggernaut is awesome. The support structure is very impressive; I think you should consider making a heavy terrain woodie (eg, The Beast) and use these bridge structures to cross large ravines and rivers. The layouts pretty nice, I can actually see it being something that Gerstlauer may build. Gersty tends to have rolling launches on their launching coasters though. Have your car roll slowly into the launch, and tone down your launch acceleration. All of your rides are accelerating at rates far beyond what even real life Intamin Accelerators are doing.
Phoenix is pretty standard. It's a very nice, realistic layout, but maybe more realistic as a Vekoma SLC than a B&M invert.
I'm also a Nazi when it comes to how brake runs, stations, and pre-lifts are configured. You should rarely be using friction wheels and brakes on the same segment, as very few real life rides do this anymore. Use one or the other. If you're using friction wheels to move a train, but still need the segment to be a block, use the purple/pink brake segment, but select the "Hide Brake Device" option. Same goes for MCBRs. I know, if you want to E-stop test the ride, the train needs a way to get from standstill to moving. You have to make the MCBR segment slanted enough so that your train will start rolling when the E-Stop is lifted. This is all merely my opinion, and how I like my rides. I think it tidies things up and just looks far nicer. Give it a shot.
Keep the rides coming though. I hope I don't come off too harsh. I thoroughly and sincerely enjoy seeing other people's rides and tinkering with them, probably more than I enjoy using NL for my own projects. I hope you take some of mine as well as others' advice and try to apply it to your own creations the best you can!
