Paul Lasaine is a concept artist and production designer for the film industry. He has worked with Disney Animation and Sony Pictures Animation and is currently a production designer at Dreamworks Animation. He was also an art director on the Lord of the Rings trilogy.
Lasaine’s blog showcases both his professional work and personal projects.
Though he mentions that he sometimes misses working in traditional paints, most of Lasaine’s current work is digital, as in the image above, top. You can find a few Photoshop brush tutorials on the blog.
If you go back a little ways, you can find some of his concept designs and matte paintings, both preliminaries and finished, for Prince of Egypt and Lord of the Rings that were done in acrylic. These, particularly some of the briefly noted preliminary color sketches, have a wonderful loose handling I rarely see in acrylic paintings.
