Imo, it's too "horse-y" ;)

Honestly kinda like the horse/crest/eagle motif, but not a fan of the boring shade of royal blue background that's used in dozens of other state flags. And the ship is just kinda weird and out of place for what's an essentially land-locked state that really doesn't have much of a maritime industry outside of Erie and a handful of rivers.

Jmo, but one of the icons in the crest should be replaced by a pretzel.
