I'm not really sure, but I think Windows systems cover the edge with the taskbar, so you would loose the frame / shadow. Personally I would rather have the image without the white / shadow frame but it doesn't look so bad this way either. (I'm a fan of simple backgrounds)
i wouldn't use that as my wallpaper*(thats how you spell it)
Its fugly.
tbh theyre just simple eye manips
try trying something a little more complex and interesting
as well the cracks in the first one look lq
the first one in my opinion stinks.. but only cause i hate the color white. there is an excessive white border around it all, and it just looks a bit clunky
the second one is pretty cool though, i like how u used the iris as a planet. again, i wouldnt use it as a background cause it doesnt go well as one, but as a larger work of art it would look great =)
