Interesting. Pretty certain I would prefer it without the line/transition in the background across the outer edges in the centre. I think it would appear to be floating in space if the background was not divided.
Thanks Paul - frankly there are a few things I don't like about it, but I'm currently taking a course where the instructor suggested the format, the colours and the technique. We will be reviewing these on Thursday morning, so I'm planning to discuss my issues with it.
He was thinking that this piece might work well if rotated by 90 degrees and displayed in vertical / portrait orientation. I suspect the line will be important if that ends up happening. These are all going to end up as prints, so gamut issues galore with these colours.
