Wow! You move quickly with large variety! This was my favorite of all the designs. Could you also add a slogan under the text? "Innovative Design with Smoke and Mirrors" You could add ", Inc." to the Blair Labs title to elongate the name and make room for the slogan underneath.
Everyone at the company is voting on this design. The variation of the "L" shading was a nice touch. Now, could we we migrate this into the black background, and do B&W also? Very creative work!
