Thanks! I love that episode, so I knew I had to draw something from it. I'll probably draw some more, actually. I want to draw the part where Twilight says "good friends!" and gives Scootaloo that weird look.
I feel you. I struggle against my need for perfection. It drives me insane to have a messy page with lines all over the place. I'm trying to dial that back, but it's hard. I have a way harder time drawing with that messy style.
That's one of the reason I ink stuff. You can take a picture and then modify the contrast. That eliminates a bunch of the light pencil marks that are still visible otherwise on the page. There are a lot more marks than you can see here on the original drawing. You can still see some of my practice drawing Twilight in the lower left.
