Very nice modern and sleek feel. Like your designs a lot.
Could you do these variations?
#1: Put DENTISTRY below the logo, and maybe raise the M a little to rise above the lines.
#1: Put NUGEN above the logo instead. I realize it won't be symmetrical, as DENTISTRY has more letters than MOBILE.
#6: Please flatten the M - shorter and wider, more like the #1 M
Thanks.
