Great horsehead Steve. The actual horsehead looks a little over sharpened to the rest of the image but it looks good every where else.

Looks great, Steve, except I'd agree with Mark about the HH itself looking a little too crispy.

Thanks Mark and Rick for your feedback. After looking at this image for several hours yesterday it is nice to have a fresh set of eyes. I went ahead and toned down the heavy handed sharpness as you suggested and posted the new version on the OP.
Thanks again!!

Yes STeve that looks better. Great work. Full moon so I will have to wait for a week to have a crack at my 2013 HH.

The repro looks better Steve, nice work, blending the Ha in is certainly a challenge with this target.

A beautiful Horse Head photo Steve.

I prefer the sharper one.
