I like #39 the best. I prefer the diamond to the square and I like the shadow under the logo. If you have a chance to play with the font and layout of the initials that would be great.
I like #44 & #45, particularly the style of the "A". I notice that the background colour of the logo lightens towards the top. Could you change #44 so that the top of the background becomes closer to the colour in #45? Thanks again for all your work.
