Brush pens and some watercolor pens for the background.
Top 2 drawn with reference.

If you haven’t already noticed, I can get mildly monomaniacal with art and want to draw the same or similar things/themes for days or longer. Romanovs, robots, Roman emperors … Wait … Maybe I have a weird letter-R fetish?! Lol
