Why is the act of drawing pixelated sans so hard

Just drew this

Using a different brush this time

Drawing on mouse is kinda easy to me also ignore the greasy ass screen this is on my brother's pc (guys is it bad if the only fnf character I can draw is him)

He's in your wardrobe

Bf icons

What do y'all think of my drawing

Brick(brush by alexsucks8k on x so don't be surprised if you see me using this brush for upcoming drawings)

Hey guys, it's been a while, Ive gotten a lot better at drawing bf, also here's an extra drawing!
