Graphite is a solid call, but a $200 tablet is kinda mid-tier for drawing, so the layers and brush settings might be part of what's slowing you down there.

Wait, 40 percent?? That seems crazy high but honestly I kinda believe it. I work at a small shop and half my day feels like digging through piles of sockets and wrenches looking for the one size I need. The shadow board thing makes sense, everything has a spot so your hand just goes there without thinking. Might have to build one for my box this weekend.

Bought a used Daniels kit off eBay for $200 and never looked back.
