This collage looks to be about GRIEF. Not intended but feelings come to the surface when doing art, not always, sometimes for me it is just doing and creating and it is superficial, other times the feelings just surface in the artwork. If I sat down and said I feel sort of sad I will paint that now, that does not always work. I miss my dog. There are lots of things to say about that but I won't.
Also some garden and maybe some altered photos. The last things that can bloom in a growing season are blooming and some have gone past peak, I do even grieve for garden, it is such a mainstay from first crocus to last mum, so much in between and so fast that it is gone before one feels they have had enough time to really take it in. What is so good about these things that I miss and will miss is it is not at all hard to do something about them.
Really I should also take a look at overdoing a collage.
