OCRemix
I Heard this from your link over on OC Remix.org i had no idea it was on Newgrounds, but now that i do im giving you a 10/10 and a 5/5 :)
I agree with Meran thats the main melody of the battle theme is hard to hear, but disagree on the fact that its not there entirely. Any fan of the battle theme can hear it in this and its awesome. It really does add a cinematic feel to it kinda.
Also, like some of the reviews on OCRemix said, you need to make this longer and build more on it :) Im gonna be keeping my eyes and ears out on you BR cause you have some talent here.
You could have a go at another version of this song with the orchestra instruments sounding a lot more powerful, with an explosive sounding percussion behind it, and a little more of the battle melody blasting out over the top and i think you'd have yourself another awesome piece right there.
Downloading this, adding you to favorites :) Hope to hear more from you in the future BR, more pieces sounding like this please haha.
Hope you like the review! You deserve all the 10/10's and 5/5's you get :)
