Pretty much putting pencil to paper really, although having an idea of what you want to draw helps.
For most of the pony characters, the head is literally a circle, so just build up from that, although (if you draw traditional like me), avoid pressing on with your pencil so you can erase stuff you don’t like.
I then go over the pencil drawing with a fine marker, (the ultra fine sharpies work well, although they can run a bit quick when they’re new).
Then erase the pencil drawing, and simply colour in the result.
Scan that and upload here when you’re happy enough with it. (We’re always our own harshest critic, and there will always be something that niggles you with one of your own drawings).
