Bob Ross is smiling down from heaven

Thanks Chris, I am planning to make a fully rendered landscape at one point or another, I'm just waiting for the motiviation required for such a piece to hit me :p

Wow this is gorgeous. I wonder how it would look like with some travelers on the grass.

The regular practice with landscapes is paying off! I think you're onto something with the way you blend slightly hue or value adjacent colours together, like you've done in the sky. Compositionally there's a good sense of depth, too. Got some Adam in there with the grass and some colour choices :b
If you were to ask me, I think you should definitely make a more refined landscape at some point, now that you're getting comfortable with sketches! Or at least with some parts with a bit more definition, as the looseness in some places could help with resting the eye or bringing it to different parts of the canvas.

Congrats
