The degree of detail that I put into 'physical' descrption, be that either just fluffy additional stuff or something that actually describes the [motion | action | gesture | whatever] in greater depth to shed light on the [mood | feelings | temper | whatever else] for the character, tends to vary, if I'm honest.
On a comms channel rather than 'actual' place (The Summit rather than The Last Gate, for example), I tend to keep it relatively minimal anyway: a grin, shrug, sigh, and so on. When the character is there physically, it's often pretty dependent on the context. If something brief suffices and what the character actually
says allows the rest to be inferred, then again, I'll keep it simple; if the character doesn't say anything for some reason, I probably make it more detailed given that there's more room with which to work in terms of a message.
Mostly it comes down to me finding that, in the case of Kyber, anyway, RP flows better if I keep the number of messages down; unless he's, say, telling a story in more detail than a couple of full messages, I don't
really like to use too many. Of course, there'll be the odd incidence where what Kyber's saying and doing don't synch too well, in which case I forego that and put speech and action in mild detail.
In an ideal world, conveying the full detail in a concise form would be delightful, but my lack of writing talent and the aforementioned restrictions on message length and so on mean I tend towards cutting corners somewhere or another. Not unlike when it comes to prose, I guess; often (well, often insofar as 'most times I write prose, infrequent as that may be') I'll omit specific description for the sake of keeping the pace up, setting a tone, or whatever the shiny technical terms are.
I tried to imagine Senn smiling.
I think I get the point of this article now. ._.
One day, I shall get one out of him.
