There is definitely a sense of style throughout these designs. Three stand out in particular. The cropping of the C, D and E are particularly visually appealing. The black in the C and E seem to have a combined wrapping yet floating effect above and around the white. The D is beautifully balanced.
The Final E works really well for me. There’s a good balance of positive and negative space. I can only focus on the white and black one at a time.
