Good to see you pushing the limit somewhat here John, not sure what the mkIII ISO strengths are but regardless for 1/30s H/H you've still managed good detail and sharpness here.
Hi John- - Nice side profile of the cottontail. I agree with Marc you did well at the slow ss. I do think you've applied a bit too much sharpening in pp though.
Hi John, as noted you have managed good sharpness and detail at such a very low SS, although not ideal, however if you see Sanjeev's image he has pushed it to ISO 6400 with excellent results - food for thought.
If you address the blue, it does help and slightly darken the lower third it does help. Looks like you also have got to grips with the aspect of sharpening within the Export dialogue panel in LR, looks good.
This is one adorable little fellow! Love the surprised look and the HA is great. I agree, this is pretty sharp for 1/30s, glad the subject cooperated and it seems he stopped in its tracks to pose for you:)
Detail looks good, nice framing, thinking I would have liked a bit more "punch" in terms of colour but I have never seen the species in real life and you were there.
A pleasing image overall, nice work! I enjoyed viewing, very much
