This fits into the 'Architecture' category, I think.
I was looking at a lesson on composition on lynda.com and one of the exercises was to look to create at 4/5 abstract images within your house, all within an hour. Images that could not be identified as whatever (chair, table, window, ornament, etc), but were purely abstract. I found it a fascinating exercise in terms of looking and composing. This was so left-field for me.
I finished two images.
I have no idea as to whether they stand up as in any way decent images. I like them, which is one measurement, but I am keen to hear from people who are more aware of and work with abstract images. Like I say, this was so outwith my comfort zone that I have nothing on to which to base an opinion.
So anything you have to say from they're rubbish to 'wow' (hopefully a bit more detailed critique), will be welcomed.
