Painting technique is certainly very important to produce a good painting.
Aqurel technique is a painting technique using aquarel with a thin color sweep, so the paintings produced are nuanced transparent.
In order to produce a thin and light sweep, it would be nice to use a slightly diluted paint.
Plaque technique is a painting technique that uses watercolors, acrylic paints and oil paints with thick strokes and thick paint compositions. So give a colorful impression on each work.
This painting technique is often used by professional painters to produce fascinating paintings and have high economic value.
