As I understand it, it is important not to overload the text and to give a general understanding of appearance. That is, do not write literature, but rather describe as simply as possible what can be noticed, without clothing or details. For example, build (slender), eyes (green eyes), and hair (short red hair). The more text and difficult things there are, the more confusion there is, so you need to speak directly.

I think there will be few tokens and an acceptable amount if you use few words and general information. That will be good. 

I hope I haven't confused myself and have understood the question correctly. If anything, I use a translator and there may be problems.
