Writing pretty=/=Writing well It's possible to write a very detailed novella about your character's individual actions during a given event and have actually written absolutely nothing at all. Get the important details down and fill in any major holes that you think need filling. Don't spend three paragraphs analyzing the density and temperament of the steel someone is using for their weapon. Such technical explanations are the realm of handbooks and instruction manuals. Also, you don't need to ramble on about the individual radius of every follicle of facial hair your character has nor do you need to go into excruciating detail about the particular fabric your character prefers their pants to be made out of in order to create a good character description. It's okay to leave some blanks here and there, that's what imagination is for. As long as you get the important details down, I promise that people will understand what your character looks like and write accordingly.
