Hi, atomy. I'm commenting because you asked. Abstractness is a fine thing to attempt for the design, however, even in abstract art or design there needs to be some consistency between one and the other to form a cohesive group, as, for instance, between m and n. In relation to m/n, the r is too large and s is completely another style and weight. Similarly, if, say D is the style you were aiming for, then A does not fit, and if A is what you were after, then M matches, but not enough. Get my point? Even in abstract type design, you need to have consistency before it makes sense.
