Again, I really like #49 & #51 as they are both classy and professional.. but, I do not like the pinkish/purple background color.. I also do not like the white circle on the left handside (do you know what I'm referring to?).
You have definitely made some improvements.. the gray is a little dull, could you try the outline (gray) with another color, perhaps reddish/brown (red enhanced with a black: complex color) or a gold...
