We like your thinking and can definitely see the hands joined. We would like to see the icon moved to the left and different color. Maybe get some blue in there. Feel free to use 4 colors. We don't like the font of Master Matchmakers either. Go with something a little more formal and elegant. We use Adobe Caslon Pro now and like it. You don't have to use that specific one but it will give you an idea of the look.
Blue represent Man, Red represent Woman, and 2 Circle opposite means Man think Woman, Woman think Man. Two different people become one. Elegant, exclusive, and easy to understand. The logo represent MasterMatchmaker with two M become one separate by collor blue and red.
You spelled Matchmakers wrong. The C and T are reversed.
The ones with the words on two lines looks too cramped. We like it all on one line better. Can you change #32 making only the first letter capitalized. Also put a space between the words or no space but different colors for each word. Maybe some more color in it too.
Your first icon was more along the lines of what we're looking for. The new icon looks too much like people. We like the idea of the people but leaving it open to interpretation by the viewer.
Stick with #46 and #51.
Can we see some different colors. The blue's and gray look a little drab. We'd like stronger, more vibrant color that will envoke a strong feeling and really engage the viewer.
