This is very artistic...Like the two viewers above I have sat here studying the shape and I have to say it has got me beat, but saying that, I do like this...Well done...All the best....Mick.
This is very interesting and I rather like the background, but I'm not sure about the unidentified object in the centre. Maybe it should be more subtley set into the background so it doesn't look quite so distinct? On the other hand, I'm not sure what it is, so maybe this is the effect you need for this one...
