Here are several related to size, from the Oxford English Dictionary's Historical Thesaurus for "the world > life > the body > external parts of body > head > face > eye > [adjective] > by size, shape, etc. > having (51)"

Some suggest emotions (saucer-eyed, wide-eyed, bug-eyed). Others are used fairly generally and neutrally (big-eyed, large-eyed). To a certain extent, you can also form other words with this format, if the noun or adjective you pick would make sense with -eyed:
When writing, attractiveness will be in the eye of the beholder. Someone who loves horses might find horse-eyes attractive. Someone who likes the moon might find moon-eyes swell. So if it seems like I've left some ugly eyes in here, it's only to not put limits on what your narrator might find attractive.
