Acrylics on aquarell paper, ca. 56 x 76 cm.
(Incidentally, this Hahnemuehle watercolour-paper is not very pleasant to use with acrylics; it has too much 'bite' and a lot of time needs to be spent filling 'holes' to get a smooth surface. Perhaps I should have prepared it with some base layer before painting on it. It is probably superb for actual watercolour use.
(Note: the diagonal streaks visible in the larger version (click on the image) are caused by me trying to color balance the digital image. They are not in the original painting.)
