What skills are yall working on?

what i mean is, what art skill have you been honing lately? anatomy, perspective, composition, colour, a specific medium, etc.

personally, i have spent years working on how to draw human heads. well not exclusively that, but it's been an ongoing project. im still not quite as good as i would like to be at it, but its much better. im ready to shift gears and work on other aspects of my art

what about you guys? what skills are you working on?
