Well, I guess it'd either be a) a window or something off panel and/or b) a light, usu. overheard.
Let's keep it simple and stick with Option B.
Here's what I have so far:
Going with colored outlines for the background and black outlines for the foreground (may change my mind and use dark colored outlines for the foreground section). I still have a lot of line cleanup to go before I tackle shadows & highlights. I also want to brighten up the background--maybe a lighter color of pink (supposed to be salmon for obvious reasons).
I think I'll take a break and draw something else for fun! I need to finish up the girl sketch for sure! :)
