Hopefully I am getting this right, the doves are possibly going to change to an owl, and the current discussion is about making the image clear enough so we all know what it is?
SweetLullably was saying about the concept of big eyes; I was thinking the dove picture is small, so a head of an owl (as already suggested) is good, and it would really just be three concepts: big eyes, heart-shaped or circular face, and a cute wee beak. I reckon you could fit big eyes and a wee beak into a circle and it'd be clear it was an owl. I personally want the owls to be a picture of Bubo the mechanical owl from the 1981 Clash of The Titans, but you can't get everything you want in life.
I do like the doves if they are kept, although I wondered where all my virtual money had gone and thought those pesky doves had nicked it.
