As far as I can tell there seems to be no tag for head/muzzle shapes that are convex and/or have little-to-no stop like these:

It's a fairly common feature across animals, but having a dished face or pronounced stop between the muzzle and forehead is more typical in furry art. Having a tag for this could help people look for specific artists or characters or it could be used to filter out styles.
What would be a good name for this feature? Convex_face gets to the point, but it's not obvious if faces that make a straight/almost straight line from the eyebrow to the end of the muzzle would be covered or not. Stopless_face is also straightforward and wouldn't exclude straight faces, but the term might be more obscure/not immediately obvious to people not already familiar with it.
