Thanks Fairy Crystal,
I'll think about all you've suggested. I wish I had more time for painting. I'm in the process of doing a big purge at home at the moment - getting rid of clutter. Finally I have space to work in again. Hopefully I can post something new soon.
Composition is something I'm not too good at - hence all the straight lines.
