That actually looks pretty good. Couple of pointers though if you're changing anything at this point:
The crest of the lift hill should be tighter, then have a gradual curve down. For example, you might wanna look at a picture of a similar coaster to nail the shaping, like Goliath at Le Ronde
B&M airtime hills can be very difficult to replicate but it should be parabolic and kinda pointy at the top
Supports look good so far. Either make the last 2 or 3 supports on the lift hill less wide or make it an A-frame support like the ones on Leviathan.
Colors look really good for the theme you're going for, but like Timmvs said you may want to go for a custom environment for something like your theme. A "bright, sunny day" doesn't fit the "demon" theme
This is actually a really good hyper, I'm surprised. As long as you make sure the hills are all 0G's and shaping is on par, as well as you use that depumper tool to it's best, you can find yourself finishing a very good coaster.
^I knew you switched building methods! I had a feeling you did, and I was right! If you're going to make anything with high pacing definitely watch the lats; even I make transitions too fast with 2+ years of experience.
I say do a Mack Launched or a Intamin Rocket. B&Ms take a lot of discipline to make, and take lots of patience. By the way the hyper coaster looks great now.
