Reddit mentions of Carlson's Guide to Landscape Painting

Your colors look great, very autumn! So you did great with those.

Another good book to read is Carlson's Guide to Landscape painting
( https://www.amazon.com/Carlsons-Guide-Landscape-Painting-Carlson/dp/0486229270 )

What he talks about in that book is how we can never replicate the full range of values or colors that exist in nature... the best we can do is have each patch of color on the canvas have a consistent relationship with the other patches. So, like, right now I'm working on a picture of a garage. I can't get the exact color I saw but I can make the shadowy areas darker and cooler (more blue) and the areas in sunlight lighter and warmer (more yellow). That way they are correct relative to each other. If you get the structure of the relationships right, then you won't have to worry about matching exactly. Let go of matching exactly and work on making things relatively correct.

Here's Stapleton Kearns on value in the landscape http://stapletonkearns.blogspot.com/2013/10/confounding-color-and-value-in-landscape.html

Anyway, I'm rambling here, but I think this landscape is a really great start, keep going. My process has been, read some books and do some exercises, try a painting keeping one or two ideas in my head, repeat repeat repeat. It's been an incremental process for me. The main thing is the work and trying again and again.

You got this, have fun! :)

It's very text heavy and you may initially feel disappointed with the lack of "tutorialized" instruction. But this is one of the more useful books on landscapes I've ever read.
