#70, 71, 72, 76 - Understand what you're trying to do with connecting the "o" and "s" but the way it's done it makes the "o" read as a "q". # 71 and 72 with the brackets and parenthesis are stronger (same problem with the "o"). #76 is not very interesting.
#75 has interest but the"O" doesn't read well. Like the concept of the tightly cropped box but need to accomplish without losing the read of the "O".
