Thanks for your work on these designs! Some specific feedback is below ...
Designs 3, 4, 5: Don't like the graphic element in the center (inverse e's) Designs 4, 5, 7, 8: The outline of the eye graphic is too bulbous at the edges/sides
Designs 3, 4, 8: not sure what to think about the all lower-case name ... I kind of like it. Looks good with the All Caps tagline. For comparison, I would like to see how it looks with "ankeny" regular/light and "eye" bold/heavy.
Design 9: not interested in this one.
Designs 10, 11, 12, 13: Not liking the graphic on this one. The font is more interesting, but might be too curvy/informal for my application. I'm interested in a semi-formal/classy font that is somewhat unique and could help with branding.
I'd like to see some designs with my name (Dr. Todd Schulz) instead of (or in addition to) the tagline. I'm also curious about how the designs would look against different backgrounds (light gray, dark gray, and black).
Overall I'm very happy with your work so far. I'd like to see more ideas on the graphic, as well as further creative thinking on the fonts. I'm excited to see more from you. Thanks!
