I use two different techniques: watercolour and oil. I enjoy both. Let me explain why.
Watercolour is a difficult and “explosive” technique. I use the wet in wet technique which means that the basic idea of the painting should be “right” straight away.
Oil painting is much more “slow” in this respect. Oil requires several layers and oil paint needs a long time to dry. I like the change between fast and slow.
I use watercolour to create impressions of flowers, fruit, still lifes, landscapes. The results are sometimes impressionistic, at other times expressionistic.
In oil I work more intuitively, from my creative imagination. Take my paintings of fish for example.
