Had a reasonable large parcel arrive on Thursday containing the print, quite happy with the print.
If I was to do it again I'd need to drop the brightness of the top yellow patch and increase some of the darker areas (flatten the image somewhat). I probably should have done a pre-print test so that's my fault really.
As it is only a 10x20" it is reasonably small, it feels stiff and the mounting plate on the back feels well constructed.
Overall I am happy with it. Considering that I can drop it to 50% native resolution and print at 40x80" 300DPI... maybe I should go bigger at some point
