This video is to showcase your VFX skills, yes?
Use motion tracking to pin that BSOD into place. It's wobbly all over.
Actually, that effect was a fairly complicated solution to a simple setup. You could use the monitor, with a pic of the BSOD set to fullscreen. 100% effective, looks more realistic, and at a fraction of the effort.
Your illusion's broken even further with the image(s) remaining visible on the monitor after it's been plugged full of bullets.
Muzzle flashes are very fiery & cartoony. What did you use for the gunshot audio, btw? Sounds much heavier than pistols.
I like the bright-ish lighting and washed out colouring. It's pretty consistent... 'til we see that BSOD on screen at the same time, where it's eye-poppingly nonmatched again.
Oh, you can see the glass fracture holes distorting as the monitor jumps up & down. (Oh, the monitor movement was was a decent gag, btw, but I bet that wasn't a vfx shot)
Those would be a few things to look at improving or fixing, before adding this to your reel.
All of the above is constructive.
