Helpful to see it in B&W. One thought. All of these logos feel a bit unbounded. I wonder if you could try creating some different borders for Entry #24? Maybe even just a simple black circle? Or something more creative and interesting?
Another idea would be to bring some green, plant life in. It could be in the background perhaps? The stones are beautifully drawn, but they do feel very stark and dessert-like.
JMC - One of my team members wanted to see some variations of #50 using different colors. Can you create a few different versions with color? Maybe some with all similarly colored stones and some with differently colored stones?
Wow! #76 really turned out great! Love the multi-color!
One small revision suggestion. I think the footprint would look better if you filled in the space, just a little, to the right of the 'g' in Stepping. Just another little stone or two, or three at the most.
Interesting solution on #77. I actually meant to add some more stones in the white space, not move the word. Sorry if I did not make that more clear! :)
Try moving the word Stepping back, but just adding a few little stones in the white space. Leave some space in there, or else it could feel cramped. Just a few little stones.
