I think I just came. This song says "GET A LOAD OF THIS BITCH!"
Very nice, faithful arrangement, but it sounds a tad too lighthearted and cartoonish. I dunno if that's the vibe you were going for, but I think a tad more menace would help this theme alot. Good job regardless!
We could Do without the Xylophone. You could replace it with a Harpsichord, or some Piano, or A Cello/ Contrabass.
Also It Would be alot more epic if you had the Timpani Along with the song
Please contact me if you would like to use this in a project. We can discuss the details.
