Welcome to NinSheetMusic! What a sheet to be submitting as your first

A couple of things to start - the
formatting guidlines. They may seem overly finicky, but it's our way of making sure we have a consistent look and feel across the sheets on our site. To achieve that, we use the Finale (.mus) file as a basis to generate the PDF off of. It doesn't look like your import worked well as the Finale file looks nothing like the actual sheet. Are you using MuseScore to arrange? If so, that's fine and we can port over the MusicXML file to Finale - someone can help with that to make sure it doesn't just plop notes haphazardly on the page.
Anyway, while I'm here, may as well give you some musical feedback too! Let's go section by section for this one because of its length - I'll just comment on the first part for now.
- The right hand chords should be rolled.
- In measure 4 the first chord should also have an E in it. Beat 2 should be an E instead of a D. Beat 4 should have an F# instead of a G.
- Left hand in m. 5-6 are different than in m. 1-2.
- The notes leading up to beat 1 in measure 7 should be ascending E-G instead of B-A.
- The chord in measure 9 is missing a C on the bottom.
- The first left hand notes in m. 11 should be an octave lower.
- I don't hear the left hand playing anything on beat 3 of m. 12 in the original.
- Left hand in m. 13 should start with a low G like measure 1. Check the left hand in m. 14 as well, that's different from how you wrote it.
- Beat 2 of m. 15 and 16 should be an E, not a G.
- Last RH note in m. 16 should be B.
- The first RH note in m. 17 should be a C.
- There is not D at the end of m. 19 RH - unlike the original Ruby/Sapphire version

- Check the left hand in m. 19 again, there are some wrong notes there.
- The chord in m. 20 should be inverted down once to keep the D on the bottom.
Just skimming the rest, the arrangement looks pretty solid but could use some polish. I'd suggest doing another pass on the rest of it to catch any transcription errors like these

Other miscellaneous things - please match the track title and composer info listed here:
[Bulbapedia] and have the game title as
Pokémon Omega Ruby & Pokémon Alpha Sapphire just like
on site.
