Here is a small portion of the giant piece that is the bane of every electronic device of mine's existence just so you know how bad I'm stress testing this tiny Lenovo laptop

I'm so excited for this painting I've been working on for the past 6 (almost 7) months to be done because this is the longest any art piece has taken me EVER, but on the other hand I think I've looked at it for so long that I don't think it's good anymore?
It has 70 layers
It has crashed one computer to the point that I had to move it onto a different one that is now breaking
The file size is around 40.6 MB, or the file size of the vanilla version of Skyrim 2x
I have repainted sections of the piece a good 3 to 5 times
The cursor in my drawing program freezes every 30 seconds and loads like the entire thing is going to crash
I have carpal tunnel now because of this painting
I think I understand one of the masters of the Art Renaissance now
Upon booting after being idle for a while and putting in my password, my laptop boots to a black screen with a moveable cursor. I can’t open the terminal or even get a dump of what’s actually causing the issue? Ctrl/Alt/Del, Ctrl/Alt/F2 (or F3) and Alt F7 do nothing, it’s like the screen is acting like the desktop just doesn’t exist
Does anyone know how to fix this?

I have a lightly used Wacom Cintiq 16in. that I've been meaning to sell for a long time after losing the pen and not having the money to replace it, but apparently I can't sell it online through Ebay or other sites since your seller name has to match your legal name on your bank card... I've had a stalker for 2+ years, so I can't do that since giving my legal name would doxx myself to the stalker when they google that name
Best Buy tried to give me $35 for a $700 drawing tablet
What other places can I sell it on?
