Not everything has to be coloured

Currently no idea for what picture to use today, so I'm just casually using two pages I just completed. The comic is supposed to be in full colour, but sometimes I'm lazy or actually felt that the scene has more impact being in black and white.

Sometimes black and white really fit a scene better than having colour (though I was told that colour is more appealing, which was the reason I'm doing the comic in colour in the first place.)

It's also quicker to complete.

So I was thinking of going back to black and white for future comics.

Not everything has to be coloured, I believe. Even if there are coloured parts, it doesn't mean that I can't have monochrome scenes, right?
