I gave Tigerstar (and Bramblestar) tomcat jowls, lol. I guess Brokenstar has his Dark Forest design here, and Bramblestar's design is supposed to be what he looks like after TBC.

I tried to give Dustpelt some gray hairs but they looked weird so he instead got a slightly lighter muzzle (imo, the gray hairs appearing on old older cats in the series doesn't make that much sense since gray is a coat color on its own - white hairs would make more sense).
