I am 95% sure this is an Echinacea(Coneflower)with the petals (pulled?) off. Perhaps a more horizontal type of crop may have made this a little different, just the 'symmetry' is a little off (bottom left of flower) in my opinion. The focus is good and the lighting has created a 'glow' like appearance, but, for me, I would like more light. I would also like to see the colors more vivid, especially the underlying green. Just for something different (with this subject) perhaps a different colored background, may have made it a better shot in my opinion. Also, I would like to see (especially for a macro) those maroon stamens(?), emphasized somehow, this is rarely seen in Echinacea shots. I liked flower02web too, but similar 'opinion' as above for that re symmetry etc. Flower01web has potential, but needs zooming out and better focus and just one stem, if any. The other, in my opinion didn't work, or at least the style doesn't suit this type/shape of flower, in my opinion.
PS just saw your post - I do not think it is Proteaceae (but if you want to know how to pronounce it click here.). Might be wrong, but still looks like an Echinacea to me. You can decide.
