desert varnish

The colours and textures are great, Ana, and the composition as a whole makes for a very appealing abstract feel.  I feel maybe a little more sharpening or structuring would allow the textures to come out even more.

Thanks Ian; I might play around with adding some structure as you suggest.

Actually, I like this a lot as presented.  Beautiful lines and excellent subject matter.  If you boost structure, I would suggest to do it sparingly.

Intersting combination of shapes, lines and colors, Ana. I particularly like the top half with the pronounced diagonal lines and alternating colors. Excellent detail. 

This is a really nice abstract. Excellent colors, shapes and textures. Works for me. 

I love the colors and the interesting horizontal lines. I have never seen anything like this so thank you for sharing this beautiful visual. It is hard to say what I would do any differently as it is so unique.
