I like to see what people have done that enables them to critique others work as simple or easy. You could say it is a favorite pass time here for me. I am still amazed by the sheer audacity of those, that have nothing by comparison, to offer opinions on that for which they have no idea on how to even begin to create!
I like how you centered the design and allowed it to overlap the border as well as implementing the solid colored border. They are a rather a unique design for a heart. I also like the "OH SO COOL hearts" you show by other users. They also are quite unique & I will keep my eye open for them!
