Random stuff.
Sketchy people practice. Most of it from browsing through HONY (Humans of New York) photography.
Studying design elements I like from clothing for some eventual character designs (plenty of geometric shapes, high collars and flowing garments). I've a world building project I've been slowly chipping away at and these were to help with the more mundane everyday people clothing, as well as to train my hand in general costume drawing. Going to have to do a lot more studies for the armoured characters later.
I had fun one day just doodling nothing but creature silhouettes. Probably gonna paint a fair number of these whenever I have the chance. Most of these were approached from the premise of the aforementioned world-building project.
