Noise-based 2D Planet optimization

This runs very smoothly on its own, but it slaughters the framerates of other elements, like a simple player-controlled spaceship. Is there anything glaringly obvious to be done to optimize it? I'm hesitant to write it to a PImage since the "clouds" are not static, unlike the planet's surface, and even only drawing the clouds severely slows down anything else on the screen. Thanks in advance.
