Gonna be honest I liked the thinner “stripes” from the older designs but more importantly, I think you have begun to lose some of the D and made it look more like an O.
It might be worth your time to take away some of the vertical line on the right to create more negative space where the eye is, and maybe move the “eyebrow” down further to make it more of a D. Just one guy’s opinion though.
This is by far the strongest Detroit Tigers concept I have seen in a long, long time, possibly ever. You do some great work
