Very very cool man. The video over all reminds me a lot of Megadeth with Mustaine and Friedmen trading solo's back in the day. Much like the song 'Go To Hell'.

I feel your pick attack and tone could have been a bit clearer on the riffing near the start but for 30 minutes practice that is great.

Your leads are very worthy of a pro stage. Very well done.

Get yourself in a good thrash band if you are not already in one.

I'd appreciate a C4C on my new demo. I reckon my first song will be most to your taste judging by this video. https://www.ultimate-guitar.com/forum/showthread.php?t=1703457
