In the past I have used oil and acrylics to make finely detailed paintings not dissimilar to some of my watercolour work.
Here I am less concerned with detail and more concerned with expression and the physicality of the paint. Some of the paint surface is thin, where you can almost see the ground and at other times impasto.
I use artist' quality paints such as Winsor & Newton, Old Holland and Michael Harding as well as others. I also sometimes grind my own pigments.
I often prepare my own boards and canvas, make my own frames, recycle antique frames and hand paint them.
