I used an old canvas that had already been used for an unsuccessful attempt at acrylic painting some years ago. I think this was a mistake as the painting ended up with too many layers of paint, to the point that the canvas weave couldn't even be seen in some places.
For the clouds I mixed a nice nearly neutral grey, then tinted with white. The yellows of the boat are from the base yellow either tinted with white, or dulled with a violet made from the blue mix plus crimson.
I tried to mix a similar grey for the water, but it ended up quite brown. Not too much of a problem because the actual Kuching River is very brown. I had a lot of trouble getting the reflections right, and even then they only look right from a distance. Close up I think they look amateurish.
I think for any future water paintings I need to use a flow medium, and perhaps also a glazing medium, to smooth out the ripples and reflections. Also need to get a wider range of brushes - I used just a large and small filbert but I think I need some flat brushes as well.
I'm using Chroma Atelier Interactive paints, which can be worked for a long time just by spraying with water. They are supposed to be easy to blend, but I haven't figured out exactly how to do it.
I still have a lot to learn about acrylics. I'll just keep plugging away.
Next on the agenda is some black and white drawings. I have just sold one at Ngaio Fine Arts and apparently the buyer is keen for at least one more. Also Artrium Gallery has expressed interest for an upcoming exhibition.
