Frankie's Origin [Sketch] (Patreon)

I've had a solid idea of Frankie's pre-world story and thought her mom would be a character people would like to see so I tried to get on a sketch of her mom and dad making her.

For a long time I've been hurting because I put so much time into my work instead of producing a ton of quicker work. I'm not sure if I should make this image fully coloured or use it to figure out something quicker, like a celshaded coloured sketch? What do you guys think - more quicker stuff or keep going with the slow/full stuff?
