Can I get some feedback on this Nightmare solo cover?

This is basically what I do to try to get better as a producer & guitar player (IMHO I’m much better as a guitar player than a producer, but it is what it is lol) — I try to re-create sections of songs and mix them, with me playing everything. This is one I just did for the solo section of Nightmare, the first rough mix.
Everything is me except for the drums and the bass, I ripped them from YouTube.
My bass is being fixed atm, when I get it back I plan to re-do the bass part myself.
I don’t like the rhythm guitar sound that I got, I’m going to change that, or maybe just EQ this one a bit.
I don’t have it doubled as of right now, and I don’t think I should…there’s just too much going on to double it.
I like the tone of the lead parts except for the tremolo picking section…I compressed the shiz out of those two tracks, so the pick attack noise wouldn’t be annoying and stick out, but I think they came out a bit mushy and I chopped off too much of the high end in the EQ as well.
Other than those things off the top of my head, I think it’s coming along really well.
I used amp sims for everything, I don’t have any real amps (unfortunately) though I would love to get a Hellwin someday.
How does everyone else handle double tracked leads?
I did 75% L/R for each except for the ending, I did 85% L/R on those, my thought process was there is a lot of fast alternate picking going on, so it could separate them more.

Appreciate any thoughts from anyone, thanks.

Lol, I was referring to the EQ of the tremolo picking section (chopped off too much of the high end)
You think the _lead_ part sounds robotic and dinky? Interesting
I did four takes total, one for each section, and each has its own harmony part except for the second
I didn’t punch in or quantize anything, I try not to do that unless it really has to be done and the part is just way too hard to do in one take
It’s definitely is something that I struggle with though, making it sound a lot more fluent between sections, I really don’t know what the best way to go about doing that is
Honestly though I think when I get the rhythm sound a little bit better and get this mixed better, the leads will blend a lot more

Thanks Ed, and everyone else as well for giving me a lot to work with.
I appreciate you all taking the time to comment and help me out with this.
