thanks my friend, the big shapes and clarity of colors worked out great in this one.
thanks Red_Force, I have had my work printed out atleast 3'x'4' and they work well especially where as D Akey pointed out there is a clear and defined design and color, I think certain works could go even double that size, when I work I have that scale in mind sometimes, other works I want to keep to about 28" x 30" for a more intimate feeling. Interestingly I have been exploring the international and national (US) art scene and found very few digital abstracts as you say. Most digital works are collage/semi photographic works, with the notable exception of David Hockney of course.
