Tim asked me to be creative with this so I've tried to make a mix up of seasons with a terrace of imps' homes.
I can see the errors, but after an afternoon of working on this, and other compositions, I'm tired. I just cannot get the selection tool to cut out the 'shrooms neatly!!
I understand your fatigue. When you know you should be able to get the results you have in your head and you just can't get there. Many of my composites end in this way. A clever image nonetheless.
