Hi Aristotle, this is very, very nice! Great critter and I really love how you have composed this. Positioning of the subject is very strong and I love how you used its lair as a frame. Good DOF and details. Excellent work!
I love it all around Aristotle! I did notice at first that the back leg was almost non-existent in the image so I did a shadow/highlight adjustment in Photoshop to bring the back leg into view. I set the shadow at 60% and the highlight at 14% and this was the result:
My only other suggestion would be to add a little canvas at the top so the circular shape of the cave doesn't feel so tight at the top of the frame. Nicely done, overall!
Nice comp. I agree with Jules about more space on top but personally prefer the darker, less visible hind leg. Adds to the creepiness of the dark cave (given a bug's view).
