That’s a great compliment, thank you!

I have no idea of your level of experience, but I can try to offer some general advice.

For me, learning to paint from life has been the most useful skill I've developed.
It’s an incredible way of increasing your observational abilities and building a visual library.
The practice of drawing scenes and objects around you is fundamental when trying to paint from your imagination.

I would recommend checking out resources related to Plein Air painting.

For instance, James Gurney is an incredible artist and teacher. His resources (books and videos) have been very valuable to me.

I like using gouache when I paint outdoors. It's a very nice medium to work with once you're used to it, and it can be quite affordable.
You can get by with just a few colors. I just bring white, black, blue, burnt sienna, yellow ochre, and perhaps a tube of yellow when I go out to paint. Limiting your palette like this is a good way to practice color mixing.

Check out this video where James Gurney paints in gouache with just ultramarine blue, burnt sienna and some white

I'll also take the opportunity to recommend the video tutorials by Alphonso Dunn, who is an excellent art teacher and covers a lot of subjects and techniques

Sorry for all the text. I don't know if this is what you were looking for.
Let me know if you (or anyone else reading this) have any specific questions.

Best of luck on your artistic journey, and thanks for playing my game :)
