An appealing image that is assumed to meet the challenge.
Fungus photos abound always have an appeal but your's is a step above the norm with the lovely detail and texture you have managed to capture. Shooting at full aperture you have got a good DOF but I think perhaps f4 or similar would have got you just that little bit more to get the smaller fungi below the top larger one in sharp focus too. It may also have got the ring of bark surrounding the fungi sharp too but I think this would be perfectly acceptable.
I like the dark background it works well but the detail on the left is very slightly intrusive and would be best cloned out to match the rest of the background which makes the main subject stand out well. I do like the texture and detail you have captured on the fungus it is perfect, well done.
Thank you for a great submission, apologies for the long delay, Sid
Wonderful detail and just enough DOF to get all of the mushrooms in. Think it would have benefited from a tighter crop that left out the black. A different angle (from lower perspective) may have created a stronger image.
8 from me (earlier) The subject's not that interesting on its own... but you've made it be very interesting with the details you've captured. Very well done.
