Drawing with a mouse isn't that bad. There are tools you can use for smooth curves and whatnot. There's a lot of detail in her helmet, but there's zero shading, so I could use the paint fill tool to color everything mindlessly. If you can visualize things, it's pretty straightforward from there. Better yet, I had A LOT of the work done already with the PTE template. I only added the hair & helmet for Midna. For Link, it was the same deal, just the hair and the hat for the most part.
Knowing some basic art shit about linework & anatomy helps, but this isn't a super hard skill to attain. Learning tools like Krita/photoshop can really up your game. I've played with them a little, but I don't know them well enough to pump out art digitally.
