Clouds Practice Speedpaint

A speedpaint of some clouds. I always avoid painting clouds because they can be frustrating and evil
I will be working on a project later this year though where I will need to paint some backgrounds and clouds so I reaaally need to practice. I need to do more speedpaints! 
I also painted this in Paint Tool Sai for a change, I wanted to have a go at using this program, I've been using photoshop for so long so I've just continued to stick with it. Sai does feel very nice for painting, I'll probably use it again
