Some cool arrangements here! I'm big on Fire Emblem so I decided to go through some of your latest Fire Emblem sheets and also your latest Bravely Default sheet because why not.
"We'd best prepare for combat, just to be safe."
So the main thing I found with this is that I feel like it could really do with a re-size, perhaps ~85% would do the trick. There's a lot going on and it with it being so big it looks kind of clunky to me at the moment. Also I feel like some of the rhythms are going to be hard to read (not your fault, the rhythms are inherently weird) but perhaps you can make it easier to read them. I'd do this by doubling note lengths and adding staccatos where possible so that there are less semiquaver rests hanging around everywhere. You could also go the whole way and change the time signature to 4/8 or 2/4: this would split the bars up and make it easier to see where the beats lie, but I'll leave that up to you. (Also now that I think about it perhaps this would also be more correct as the time signature changes are perhaps better realised as different phrase lengths?)
Opening - History Unveiled
This is a really nice looking sheet! There's one major thing I'm confused about which is the section bars 13-17. I'm not clear on whether you are expecting the performer to use pedal in this section because in bar 15 you left out a note in the top part on beat 3, which suggests to me you don't want to performer to use pedal, but the following bar is impossible to play as written without pedal. I feel like adding pedal signs would make it clearer to the performer exactly what they should be doing in this section because to me it's confusing at the moment.
(Also I'm not sure how you'd make the glissandos on piano sound good since I have no idea how to do a glissando at that speed quietly, but I feel like that's a minor issue.)
Shrine Maiden's Prayer
This is another really clean looking sheet! A couple of minor points though:
- I feel like it might be better to hide the 8vas and write a note at the start saying something like 'play right hand an octave higher than written' since they're there for the entire piece.
- I'm not convinced that the G double sharp in bar 14 is harmonically accurate and I think it should be written as an A.
