It perhaps lacks a little variation and seems repetitive at times... I'm not a master of this style of music, so don't take my commentary at face value.

But the choice of electric guitar and the energy of the style go well with Yuwal's theme.

I like the use of the distortion guitar, it definitely adds to the theme (perhaps Yuwall distorts the world around it just by being present!). And you make me realize I should really use cow-bells more xD. I do have to say that it feels more like a metal song than an enemy encounter. I'm not sure why actually.
At first I felt the song would be inappropriate given the slowness of the initial bass, but I'm glad you quickly followed it up with some quick drums! It does feel a bit to me as if it could use another instrument... perhaps another instrument to be played in the background, like the bass guitar. Anyway, I like what you got going here, well done :D

This might be hyper specific but this song reminded me of a game I used to play on the Wii called Exitetruck. I don't even know what that games music sounds like but this song still reminded me of it.

SA2 type beat. I love it!

Love the bass tone on this one! Really sets the song up right and ready for takeoff

Nice song! I noticed you said you loved cowbells, and I personally think the cowbells add a nice touch to this piece :)
