Acrylic on canvas. I knackered up my wrist playing in goal when I was a bit younger (multiple fractures), so my hand tends to tremor unless supported, so I moved from oils to acrylics because they dry within 10 mins, meaning I can rest my hand on the paint without issue (oils take weeks to dry). If that makes sense.
As much as I would like to be able to paint in a more 'artistic' style (or so some would say), I ended up in the habit of more traditional portraits - probably because I studied Rembrandt and Singer Sargent in school. When you then move into acrylics, it's hard to get the same soft blends, so I just ended up in sort of my own thing. It's not something I do regularly, as I can tend to knuckle down into anything I do and spend all of my free time until its done (including jigsaw puzzles, which I'm banned from doing at home now by the mrs lol).
This was my Soldado, done when I had 2 days off around Christmas a couple of years ago. Others would take me 3 or 4 weeks, although I have taken 2 or 3 years to do some.
That's as far as I got with that one, a lot of mine tend to be black backgrounds with minimal detail outside of faces.
