>>4092582That's... not a good idea.
Imagine it this way: you just adopted a puppy. With enough nurturing, love, and care, you expect it to live for 20 years. You want it to grow into a well-rounded member of the family. A friend.
What you're doing right now is the equivalent of learning how to manicure your puppy's claws. Rather than learn the basics, like feeding it, basic commands, washing it, etc. you're going for a specialized area. Right now you wanna be a swiss army knife, rather than a scalpel, if that makes sense. Have a basic understanding of ALL of the human form, not just hands.
And ditch the Gravity Falls style, it's like you're asking to be slapped in the face.
