I did a search to see if I could find something similar, but nothing came up. Maybe I used the wrong keywords, but still, I found nothing.
I have a few "art of" books and one of my faves is "The Lord of the Rings Sketchbook" by Alan Lee. Now, is it considered good practice to copy out such work in terms of gaining an understanding? Like, I really admire Alan Lee's pencil technique, and of course the images I see of his from that medium.
Or is this simply something one could do in an "artistic downer/frustration" to get the juices flowing again for some real study?
