Ilike the bigger cactus in the design. I also like the idea of the mountains although they almost seem a bit more like mountains from Switzerland than what we might find in Arizona. Also, I do like the color scheme but I'm looking for the main colors to be more along the deeper red / marroon.
I also do like the sun color that you have - looks good. The main purpose of the logo is mostly for use on my website, so something that is more spread out rather than round or square-ish would be best.
Also, if there were a way to include a silhouette of a person that would be good as the site pertains to my individual expertise.
Just throwing the overall picture out to you.
Let me know if you have any questions.
