#17, 33 and 83 - "P" appears too extended because the white 'eye" of the "P" breaks through the leg of the "P". What if the box that butts up to the opening extended into the "P" to complete the leg and leave the "eye" as it normally would be - may get the same interest and "box" - OR - Make the height of the "P" oversized so that the green box (#17) is taller and has a little more impact? Need to be careful so that it doesn't look totally out of proportion to the "ost". #33's color ,scheme is too subdued, 17 and 83 are better.,
#41 - Is interesting. Does it need a background or some holding device such as a rounded corner rectangle to help separate it from any background?
#132 - Consider moving the green rectangle to the left so that the eye of the "P" stays white. Green would overlap the blue leg of the "P" and butt up to the eye.
