This is my absolute “go-to” list for learning and inspiration. I immerse myself in it and try to get into the minds of the master painters. I hope it’ll help you as well.
Pinterest Board: (this is my gallery wall of favorite master artists) http://www.pinterest.com/teveman/favorite-artists/
Clyde Aspevig: (The best plein air painter I’ve seen)
Joseph McGurl: (Amazing plein air painter)
John Cogan: (incredible acrylic landscape artist)
Works of Anders Zorn: (great artist for incorporation people into a landscape)
John Pototschnik: (check out his blog for an excellent resource of interview and tips)
Cyrus Afsary (great balance of abstract and realism in landscapes)
John Singer Sargent: (a must for everyone’s art list)
I also Google images for Richard Schmid (his website doesn’t show many paintings)
For learning how to paint figures, I often refer to Vladimir Volgov (Google images)
Mark Haworth(Central TX landscape painter)
Frank Serrano: He does landscapes often with a western theme. Most of his work can be found on Instagram (@urbanbrush), not his website.
