Abstract Thursday...

...portraying depth - (mis)leading lines - and all that...
I was doing just lines but the photo was too pretty for my liking...so experimented with layers (never used layers before)...and misleading lines...the circles...three layers are here. I used the Trigraphy app.
I didn't spend long for me on this, because I have been researching all day and am dog tired...
The original is in the extras. This is done on my iPad2
