How to Not Art

WIP + I have a Q

So that's a WIP of Penny from RWBY that I'm doing for my friend Noah

Here's the sketch

(tbh,,, the lineart looks better than the sketch) (should I wait until my markers ship to color her?? idk man it's not like I'll see Noah any time soon lol)

And my Q!!

I really really want to do commissions because I love drawing and I love money but

How do you communicate like that,,, solely online

Because I'm 13??

People won't just give me their credit card number?? And it's not like you'll send me money in an envelope (you're not getting mah address anyway)

And I don't want to sound like a creep,, bc since I'm so much better at traditional than digital I'd have to mail it and ask for their address and ???

And my art probably isn't even good enough???

And I can't spread word of my art bc my parents won't let me or my sister have any social media at all -.-

Normally I wouldn't care but

Seriously

Let me advertise my art >:U

But anyway

Should I do commissions??

Or should I stick with freebies for now?
