I think they're nice. They may not be conservative enough for my use (not sure why a square seems more uptight than a circle, but it does). But they're definitely worth putting in your portfolio.
Here are some new ideas. Made it more classical and serious. Some of them are hard to tell the difference because the size of the image, but the thickness of the separating lines are different to even out the balance. Hope you like them.
I think you got it with #88. Two requests... (1) can you add a comma after group and drop the PLLC down so the bottom is even with the rest (as opposed to the superscript)? Can you double-check the color. The "lg" looks a shade lighter than the stripe in the box). Could be an optical illusion, but if it's not, can you make all the lettering the same color as the stripe on the far left? You can email me at wtmorton@yahoo.com to let me know when you put the changes up so I can end the contest.
