Weak Antenna Signal ;)

Works for me, Howard. Good use of the shade to produce a nice clean bg. I also like that the BF is on an orange zinnia making this a pretty much an orange and black bicolor image. Orange and black contrasting colors coordinate well as evidenced every Halloween. 

I don't see anything weak here, Howard.  I did have to pull out a field guide and study to see how to distinguish this bf from a Monarch...  I like that there's just enough difference between the wing edges and the background to see them, but that the differences are subtle.  As Scott says, the color coordination with the flower is a fine bonus as well.

Even though the antennae appear to be lost in the dark at first glance, I can still make them out in the larger image, so  "fine-tuning" your vision makes up for the "weak signal."  ;^)  I think a brighter or more colorful background, or some backlight would have produced a clearer documentary image, but this one is more unique and quite attractive.

I like the inclusion of the orange flower.  It accentuates the subtle rusty color or the queen.  A monarch would be the same color as the flower.

Hey Howard,
As with most 'True Artist' you are your own worst critic . . .
You see a lost Antenna while I see a delightfully unique image with sweet detail, an outstanding color pallet and a wonderful background that creates and very enjoyable and subtle contrast to the two subjects of this well balance composition. The Antennae are plenty visible in both versions to my eye.
This image did give you the opportunity for a really cute Title and you played it well my friend . . . 

You have to do some really fine selection, but you can brighten the antennae selectively, if you want to. Not sure if it would be an improvement; the photograph is fine as is.
