I'm writing my very first short story. a romantic fantasy, and sometimes when I try to describe the actions of characters, their body movements and hand gestures, and their eyes and facial expressions, I find it really hard to find the right words to communicate my imagination and what I see to the reader.
Do you have any tips about that? What do you personally do in a situation like this?
Update: Thank you all for your answers, it helped a lot. To give more details about the situation, I am trying to write a scene where the hero is stabbed in the heart by a dark angel and I don't know the verb for that scream of pain he will let out once he's stabbed, I tried searching the thesaurus for synonyms and found some verbs like groan and wail but when I searched their sound, they were not the verbs I'm looking for (English is not my first language so I googled it)
Another situation is when the heroine is rescuing the hero and bringing him back to the healer, I wrote: " 'Guardian help...' she said in a panicked voice" I don't know if there is a verb to shorten "she said in a panicked voice" description.
I am sorry if my question sounds silly, it's because this is my first story writing piece.
