Hi Vikopaulum. Glad you like my work, it's always nice to get positive feedback!
Sadly not had a lot of spare time to do many more recently, but will try to get the paints out again soon.
As for what materials I use, I use a combination of acryllic and oil paints and some fine brushes. If you're thinking of having a go, grab a few commons to start with and just experiment
Hope this is helpful!
