3rd one is best out of all of them try to make the render on the first one more visible..is it an eye?
first=7,5/10...reduce the black pixels with levels or curves..add more depth and color...and a 3px border second=7/10 brushing ain't bad..but not accumulating with the render..render can be blended better and text is ok third=8,5/10 brushing is nice and render fits...border needs less overly and i suggest a pixelfont ... good work
