The percussion's not too bad! The kick is nice and punchy. The only things that stuck out to me were the cymbals which they could probably be much quieter, and your bass gets kinda drowned out when the song gets busy (0:30 to 1:20 for example). The progression is pretty interesting here, the guitar chords have this muted aspect melody-wise, and they give an ethereal tinge to the music. I love the pad that kicks in about 1/4 of the way into the song. Using this "Ogun" thing as your sole source of melody is a really neat restriction and I think you manage to make the song sound fresh and complex even with just the one source.
