Tutorial: Sunset sky

I'm back at it again with a tutorial. This one is for some clouds in the sunset. The tricky thing with clouds is that when you think of the colour of clouds, you usually think of white. However, that's just one of the million of colours they come in.

When the sun is low, you get more contrast and parts of the clouds will get darker than the sky. At the same time they're sometimes semi-transparent and you have to take into account the light shining through some parts of them.

I tried my best to make an easy tutorial where I added some of my thought process while painting skies.
