We really like your entry #153. It's a very strong symbol with emphasis on the UR that we are looking for. The tagline is important to us if you could enlarge the size a bit. Also wondering if a "gear" could be incorporated into the design. We are using in marketing so this element would be a good edition. Thank you!
Nice! We like #186 and #179. If you could simplify the background on #186 so the letters are easier to read that would help. Maybe keeping in grey tones so the red star really pops. We like the subtle gear in #179 but it's a tad masculine. Go to be careful to appeal to women too :-) Very nice work!
