Gosh, autumn is beautiful round these parts!
When we lived in Canada the thing I really used to notice when we came back to the UK for visits, was how colourful winter was. I don't think you really notice it until you have lived abroad.
On the Albertan praire for six months of the year things were a bit monochromatic. First the snow and then a spring that took ages and ages to arrive.
In the UK there is (mostly) always green grass, lichen on trees, berries in hedgerows or nuts on the ground.
My graphic design course kicks off with a "visual awareness" module next week... I'm in practice already.
