Interstellar Weekend, and another alien landscape

Still churning out Interstellar fan posters on this end, drawing on my vast stock of ice macro-photography:

The difference from my first fan poster is that I've started using Procreate, a graphics app for the iPad. 

After two weeks, I've decided Procreate combines the best features of the five graphics apps I've tried so far: it has a fine set of drawing and painting tools, high resolution (up to 4K images), and excellent options for compositing layers, such as hard light, soft light, and color burn. I give it two thumbs up.
