Peter,
Thank you for your entry. This is a great start for a design. I like the brown tones, we are definitely looking for something that will convey a stony look. I like the emblem because it is very clean and unique. I am not quite sure if I'm crazy about what is in the emblem however. I do like that there is a lot to look at, but I think I would like it more if it were a pile of rocks or one rock or something. Can I see some variation on this part of the design? Font presentation looks great. Nice job.
