Height and build can be summed up by a character's build adjective. I.E. 'Hulking' 'Puny' 'Average' etc. This is visible on a look command at the character, which will return something along the lines of this:
PERSON (average female with HAIRSTYLE wearing SOMETHING IDENTIFIABLE.)
Overall description of your character can be summarized in @describe. Personally, since @nakeds are a thing, I like to put information like how they walk, how they talk or posture themselves, gesticulate, that kind of thing. Information you'd take in with a quick glance, that lends character and depth to your toon.
For @nakeds you really need to cover your bases on the essnetials. What color is your hair, how is it styled? What color are your eyes, are they beady, large and innocent, darting madly about? What's your facial features, does your character have resting bitch face, are they weasely, are they wizened?
If you want to go lazy, just do the obvious and commonly exposed parts. Head, eyes, ears, hands. You don't need to fill out every naked slot, only if it' something memorable. Neck is a good example. If you don't have a scar or tattoo or something, it's an easy assumption to make that your character has one, and it's fairly average. No need to write out 'has an average-looking neck' in the slot.
You can also describe pairs in a single nude slot. Both hands, both eyes, ears, feet, legs, arms, etc.
No need to write "Has a blue orb." in each eye nude, otherwise the repetition will look a little silly.
These are just some examples and tips from my time here! Please be considerate to artist characters if you come in the dome with tattoos. Get them 'retouched' and have them codedly put on your character. Make your character unique and awesome! Average, unremarkable chums are booooring!
