Littlepip and Homage. Should i color in?

[Twiliscael 3,960]

I recently made this picture of Littlepip and Homage. Homage is whispering something embarasing into Littlepip's ear, like always. Anyway, i was wondering if this was good enough to color in? If not, any suggestions? Thanks!

I like it. I don't know about colouring it in. Its your artwork, chief. Colour it if you want.

That's really nice and clean lineart, so there definitely aren't any obstacles to coloring it in. I say do so, personal preference.
