water color still life study

For this still life study I used not satin/smooth paper but a more rougher surface and I like it!
Untill now I had so much trouble with working with such kind of water color paper, but I think that it helped a lot that I have painted with oil color the last month(s).
This is only a study in working with water color but also with composition and such. The white you see is the white of the paper, I did not use white paint.

I have so much difficulties with backgrounds and composition. I have purchase a beautiful book about composition and I just received it. I can really recommend this book, it is called: "Mastering Composition by Ian Roberts". A beautiful illustrated book, I only looked through it but it seems to me that it will be a great help to me.
