oil painting- advice please
Hello, I've been doing some colour practices in oils lately, from life. The problem is everything is looking wishy-washy and grayed out. I've got the feeling I'm not defining the forms enough and I'm using too much white. But I'm not sure how to change things, I don't want this way of painting to become a habit.
Here's what I've used:
linen style oil paper
hog bristle size 10, sable flat size 8, synthetic filbert size 4, synthetic rigger size 2
phalo blue, chrome yellow, crimson, titanium white (yellow ochre and raw umber too for the gate picture)
The two still lives were painted indoors at night with just a regular bulb. The plein air one was done this morning.
I start of by drawing in the basic forms with raw umber and turps, sometimes rubbing in some raw umber for a base. Then I put down one thin layer of colour and do the final layer with thicker paint. The jar and fruit took 2 hours, the pears 1/2 hr and the plein air 2 hours.
Any advice on how to improve in general would be much appreciated, thanks.
