Chris Davies has ocular albinism so finds it hard to see small detail, but although his portrait was "impressionist" the overall shape was wrong. I also liked the "skeletal tree" even though the branches were not 'correct' but sometimes the impact a painting has is sometime later spoilt by over-analysing the proportions.
I once viewed a painting in an art exhibition which made my eyes water. I just had to buy it, and it is now on my lounge wall. It was not until my husband poiinted out that the perspective was not correct, I then noticed it too. But the rest of the picture is so beautifully painted, that I forgive the artist :)
My favourite artist in the challenge is Anil (I think that was his name)
