Axl's theme - Across the lake of fire

I wanted to make a piece that fused blues and metal because of Axl's 20th century origins and guilty gear's metal heavy soundtrack, but the only thing I ended up keeping was the 12 bar blues structure in the main section of the song.

The guitar melody was not recorded on a guitar,  but instead on my bass pitched up by 2 octaves.

This is my first time making metal, so any constructive criticism from any metal fans would be appreciated.
