Trees in winter

Kenneth Armitage: Five trees (line) Richmond Park (image from here)
There is such beauty in a nude tree.  Shrubs, hedges, and trees show off their wondrous naked structure in winter, and especially so in snow.  I particularly like Kenneth Armitage's two dimensional renderings of trees - the drawings are so sculptural.

Perhaps my favourite is the collage with cut-outs below.

His large sculptures of trees, however amuse me;

I cannot take them seriously, even though I can see that they are the logical development of his drawings and his small sculptures - which I do admire.
