nine out of ten; okay hear me out, i know you dont like the design and ill agree that its not the best, but i love her purely based on her story and the character blurb youve given. but anyways! in terms of design, id suggest keeping the light colors because i love them, but i feel like a split cream/white look would be nice for her? or a slightly darker brown color with creamy spots, think of vitiligo or something similar to that. id suggest maybe something like a gold color for her eyes too, since i feel like thatd be neat?
if you do go with the gold eyes, maybe make her horns a golden too- or put a gold band around them or something! i feel like the hair could stay the color it is, but if you do go with a darker brown for vitiligo maybe make her hair darker colored as well, otherwise just keep it the same in my opinion. nails are the same as the eye and horn situation- id say you should make them the same color as her eyes possibly? i feel like the bright or unnatural kind of accent would look nice!
for some reason, i really like the thought of her having a tattoo that you cant see at initial glance would be pretty neat? say, something on the back of her neck or the inside of her upper arm! and it doesnt have to be complicated or anything, maybe just a butterfly or heart or something like that! totally like the idea of a beauty mark or something or keep the marking that you have currently on her chin because im absolutely digging that! otherwise, i think thats all i really can suggest for her off the top of my head? sorry im not the best at describing designs or anything and that i didnt really help give a design beyond colors or anything.
anyways, i absolutely love her character and really do dig the idea of her and what kind of potential she has! best of luck getting a good design for her!

lorca is a giant dragon auditor who travels through the universe in search of planets to judge. hes considered one of the last world eater dragons and, as his name states, he will not hesitate in eating an entire planet if it doesnt pass the test that auditors like him administer. he has a pupil named lyre that usually scouts planets out for him and he has the ability to make himself small enough to travel around on most planets normally, but hes still your typical large dragon size.
he carries maps of the various universes that hes been on because, despite being a giant world eating beast, he gets lost very easily and wouldnt actually be able to go through a universe without his map because he would go in a loop around the same planet multiple times. overall hes really fair with his judgement and only eats the failing planets as a means of creating room for more planets to survive, thus hopefully carving the way for a better planet to come up.
