I've been painting some drawings in grayscale to save time. I need to finish my book as soon as possible, and not having to choose the colors and hues is a good thing for me, since I can't paint as you all know.

Anyway, I'd like to know what do you guys think about this. Is it a bad idea? Does it look weird or tacky?

When I was a kid I saw some old dino and prehistory books with B&W illustrations, and this is some sort of tribute to them.

All comments are welcome!
