Hey, glad to see you here :D. And thanks a lot for the compliments!
My accelerando was actually inspired by your 'Fossilized Relics'! And as you may have figured out, I sped it up from 120 BPM to 240BPM, which you can simply halve by doubling the duration of notes ;). It indeed gives a very smooth transition back, I'm very glad about it (though I think your accelerando was even smoother and more epic). Thanks again <3
