Well The beginning could use some editing. I don't really like to review just videos of just solos. Your playing is ok. Its a little muddy in some spots. Guitar is a little loud in the mix but still its not to bad. I like the flying guitar/showmanship at the end but also I would rather see you cover a whole song not just the solo.

Nice guitar and nice tone. Its a luxury to hear your playing over the song so clearly. The alternate picking at 0:21 could use some work, but i applaud you for mainly using your wrist to pick it rather than your elbow, and it sounds like you know the positions well. The arps at 0:26 were good, and you did well with most of Alexi's whammy bar stuff, which tends to be a pain for most lol. Good job man, bodom solos arent easy! You did great!
You have nice tone. At first it sounded somethink like a compressed synth sound but it suited the solo well. Some faster parts would need more accuracy so maybe you could practice those with guitar pro:s speedtrainer and really concentrate on small stuff. But in the end it was very good cover of the solo and as said before the whammy stuff was accurate

As previously mentioned, the tone and mix are great! Overall I felt you just need to polish up the details of the playing. The alternate picking run was a little sloppy and not clear, but you clearly have the capacity to get it done. I'd just play it through with a metronome starting a bit slower so you can get it sounding really tight. Alexi plays some tricky stuff though, and i think with a bit more work you can nail this! Good effort, keep rocking
