Hello Ken ,Sorry you have waited for such a long time to get a response must have missed this ,
1.When choosing specimens try to choose specimens that are perfect your
chosen specimen has a chunk taken out on the edge which detracts from it
2. Watch your point of focus and aperture settings close up and macro photo
work will show up any faults 100 fold,your 2 pic is the best better focused
and you have some detail in the log which the fungi is using as the host.
Other than these points Ken image 2 is the best of the pick image 1 you have got to close and the image is out of focus there is no part sharp wether its aperture settings or a focusing point.
So image 2 does it for me you could improve on it slightly by cropping in slightly to the left and the top and tighten up on the main image otherwise well done
