Nice designs. Can you change the abstract mark in #81 to have more of the "C" visible, or in a less slanted position? Perhaps also one with the "C" a little more square (not fully square) so that the "L" is a little more angular?.
Also, #83 and #84 we would need to have the "L" look a little closer to a traditional "L"- comments around the office are that it is a little too abstract. Keep up the good work!
