Ahhh Blazing Blade. That was the game I started with when I started arranging as well, it's a really good choice for getting the hang of things I think (also the music's really good as well.) I've been meaning to arrange this track myself for ages but I never got round to it, and now I don't have to! :P
For better or for worse, that means that I've gone through this arrangement pretty in-depth so prepare for feedback:
First things first, let's get the notes out of the way:
-Right hand is great, although personally in bar 8 I think I'd drop the lower notes and just leave it as a single melodic line throughout. It keeps it consistent with the rest of the sheet and I don't feel like the melody needs the extra weight of the octaves particularly.
All of the rest of the note comments are about the left hand.
-Bar 7 I think the first dyad is E - B (rather than E - G#) and the second is Cn - G (rather than Cn -En).
-Bars 13, 15 and 17 I'm hearing the dyads as G# - D# (rather than Bn - D#).
-Similarly in bars 14, 16 and 18 I'm hearing the Cns as Ans.
-In bars 14 and 18 the low Cn I'm hearing as a low Bn.
-In bar 16 I think there's an En on the second note as well as on the fifth.
-In bar 19 I think the low Cn is an En. Also once again I'm hearing the Bn and Cn in the chords as G# and An respectively.
-The top notes in the left hand (2,4,6,8) I'm not convinced on. I think I can hear the bass being doubled and also a G# -> Gn -> F# -> Fn movement.
Now that's out of the way I can talk about interesting stuff instead.
-Firstly, congratulations on being a proud owner of finale v26
and now I have to convert all of your files on submission but in all seriousness just be aware that for some unknown reason the articulations placed in sheets made in v26 corrupt when opened in previous versions of finale which is a massive pain, but luckily owners of v25 (like myself) can easily reset them which I'll do if and whenever you submit a sheet to the site (at the end of the process.)
-Speaking of articulations, I think it's generally preferred that if you have a long note short note pattern that you use a slur rather than a tenuto on the first note which you might want to consider for places like bar 20.
-Staccatos on the crotchets in bars 17 and 18 perhaps?
-It's good practice to avoid dotted rests unless in compound time or if it's a really weird case, so I'd change the dotted crotchet rest in bar 7 to a quaver rest followed by a crotchet rest.
-Everywhere you have a low note followed by a staccato chord/dyad you might want to consider putting a slur between. It might just look a bit clearer/intuitive/readable that way. Like this:
Though you might find them a bit of a pain to place in a way that's aesthetically pleasing (certainly don't leave it as the finale default because for gaps this large it doesn't do a very good job at all.)
-I'd just like to point this out (because it's so rare) but it looks like you've followed the formatting guidelines perfectly, so thanks for that!
I think that should be everything, so congratulations on your first arrangement and thanks for picking a great game and piece! If you have any questions, be sure to ask. (I'm generally around, but there's never a shortage of people to ask.)
