oil paint still life apples, first stage

I already tried to paint this still life, but I was not satisfied.
The canvas (a cheap one) was so rough that it was not nice to work on. The paint sunk in immiddiately, the paint did not flow and my precious brushes got ruined.
So I took another canvas, still not so expensive:-)))), and I put a layer of Gesso and an layer of acryl paint on. I mixed Umber and white. And it is a lot better to work on.
Not too slick and still some thooth.
I tried to paint a bit more loose and after adding the brush strokes with color I soften a bit the edges of the brushstrokes and mixed the colors a bit.
I used almost no medium, in case the paint was a bit to stroppy I put a tiny bit of medium at my brush (half terpetine, half standoil)
I have a jar already mixed, ready to use.
I am almost half way now, to night I will try to paint the left side of the table and tomorrow the background.
In real the apples are darker and more volumpteous like real apples.

It is so difficult to take good pictures and to get the right colors.
I took I think 30 pictures to get this one.
The painting is 30x40 cm, I find this a real nice size to work on.
Not too big not to small.
