Hey, you have talent and are clearly honing your skills. I'm a stranger, but please keep going.

I won’t even finish this..thing

Honestly, just do what you can. For something like this, do it when you feel like it and when it's fun, that's the point of a hobby! But if you've cultivated discipline, you can buckle down and do some if you have the energy but not the motivation. Either way, all the best on your art journey!
