His clouds are great. If you look at this sample of his work, there are some clear indicators that they are using a mixture of texture brushes, and also the smudge tool in PS to flick some little wisps off the edges of the clouds. What makes the clouds so great is the approach. It's painterly, and usually involves 3 main areas of tone. A shadow portion, a strong highlight portion and a middle tone blending between the two. After that it's a mixture of texture brushes, or smudging, throughout all the samples I've seen on DeviantArt. So using a mixture of a textured brush I made this first by painting with the textured brush and building up my tones. I started with a dark tone and worked my way towards light, similar to the samples you mentioned. Here is a link to my PSD file, and the .ABR Adobe Brush I used to make this. Cloud Painting.zip - Google Drive After getting the blocking in for the shape and shades. Use the Smudge Tool, also using a textured brush, to blend, swirl, and move things around. Using about 50% pressure in the options bar. After this I used the smudge tool set to about 10%, and turn on the finger painting option. This allows you to not only smudge, but pick up some of the shades from the last few pixels you smudged. Just like finger painting, the tones travel with your next smudge stroke causing some blending to mix together. Just remember, real low pressure here! In some of his posts he says he's using photos of clouds and converting them into a Photoshop Brush. To do that, you just crop an image to a cloud you like. Make a selection of it, preferably after removing the background, and then going to Edit > Define Brush Preset. You can also do a google image search for "clouds transparent backgrounds" and turn those into brushes. Lots of free ones online! Good luck, and happy painting!
