I like #4 a lot but the magnifying glass may need tweaked. It shows I am searching but initially my mind said Private Eye. Not sure the client would get that right away. The other two I wasn't as sold on. I did like the pop of green. Tend to like brighter colors not darks such as burgundy and grey although that is Ohio State colors...lol!
Can you play with a combo of #47 and #35. I like the blue on blue color. I like my name better in 47. You are close...you have done a lot of designs for me and I would love to see it payoff for you!!! You are definitely one of my top 3 but needs a little to be number 1! Thank you for all of your hard work.
