Its always good to see the little guys too. Comp works well, and I like the detail. Of course, the clover leaf puts this over the top. If this were mine, I would try and blend away the darker area URC.
Nice little fellow, I agree with Stuart about the dark patch, however I would try if you have the IQ to crop closer to also eliminate more of the OOF rock in the foreground.
This is a great capture of this little fellow. I had a chance to photograph them while in RMNP, and they are very quick. I agree with belding in the URC. This capture is extremely sharp and I love the details in the fur and wiskers. It's nice that you can see the paws and the clover makes it pop.
Ignacio - Great detail and the clover just makes it. I agree with the others regarding the dark spot. I'm seeing a slight halo along the top of the head and down the back.
I like the composition very much as is Ignacio and wouldn't crop if it were mine. The green clover really pops from the otherwise blandish colour scheme and is a sublime touch. Good detail all round.
