I've been surprised by the amount of submissions where the melody itself is clearly not the focus, despite this being the melody jam. That problem is not present here: your melody is proudly front and center, and the melody is good. I still have dozens of submissions to go through at the time of writing, but so far this is tied for my favorite one.
Melody Clarity 5/5
This isn't up to debate at all imo. The melody is very clear, easy to follow, easy to hum or sing (which is always a compliment when it comes to melodies). I wouldn't be surprised if even after I've rated all of the submissions this was still the best melody I'll hear in this jam.
Melody Impact 4/5
It's memorable, well written and carries emotional weight. The only reason not to give full marks here is that the same melody repeats a lot. The entire near four minute track is just the same great melodic idea arranged in different ways, which starts reducing it's impact for me.
Composition 4/5
All of the individual parts are very well made, and the flow from part to part is very clear. There are ups and downs, a sense of growth, and a story being told and that's almost all I could ask for. Only thing I would think of adding is a clearer alternate section, a more contrasting melody with a different mood to break up the repeats of the main melody. I guess there already are two distinct melodic ideas here, but I'm maybe thinking about something more drastic that really takes the track to a new direction?
The very end was lovely though!
Listenability 5/5
This category is cleared without any problems.
Correlation to Theme 5/5
I think the Weapon of Legend being the bow and the arrow is a fantastic idea. I like how you used the word "rain" in the title and how it can relate to arrows. I can't really think of a reason to not give five stars here.
I think this track, especially in the context of this jam, is fantastic! It really sounds like a theme from a fantasy story. I don't think I have any further notes, great work!
