Nice shirt!

Real design criticism requires some domain expertise, and possibly not fair to put upon the general audience as a prerequisite for giving a bit of feedback on something they are consuming. It's more the designer's job to know how to draw meaningful feedback out.

Kind of like asking if someone liked a movie, ("I didn't like it, it just didn't move me") and then insisting on an astute screenplay assessment to validate their opinion.

Personally, I like the shirt. It appealed to me immediately, because I like solid color shirts, usually red black or white, with single pieces of iconic art on the front center.

A "real" assessment of the design would require understanding the requirements and goals, then making a judgement as to (1) whether they were met, followed with (2) critique on the way in which they were met.

Again, nice shirt!
