We really like the depth of #52. Ultimately we would be using the graphics to the left as an Icon, so it would be nice to see this moved to the left a bit and maybe grouped closer together.
For #45 and #50, could you slant the graphic the other direction (to the right) and then slant the font to right as well?
#120 is lot closer I think. I'd like to see the graphic and the font have the same degree of slant. I'd also like to see #120 with the font used in #42 (but slanted/italic).
Have the spheres start at the bottom left of the 'P' and with some looser spacing of the spheres and a tighter arc, have the spheres curve in and under the whole logo as if cradling it, but ending in a straight path, don't curve back up. The spheres imply growth and forward motion, by having them curve under and cradle the logo they can then also show support.
When they curve under the logo be sure the line they take under the logo is straight, I don't think it would look good if it then curved back up (as in a hand holding something).
