Comic book sound effects help
I'm going over and revising my graphic novel for publishing at the moment. I've taken a bunch of notes about what needs fixing and how but I need a little help. I've had a couple people say it's too "silent". I don't want to add too many sound effect bubbles because that seems kitchy to me but I do want to add a few important ones but I'm not sure what words to use. Could someone in the know help me?
Here's a couple scenes I need a bubble for but I have no idea what word to use.
1. A man has been grabbed around the neck from behind. He attempts to cry out for help but it doesn't come out clearly. What should his speech bubble say?
2. A man has been shot in the knee. He needs to cry out in pain somehow. What should be in his speech bubble?
3. A woman sees something surprising and gasps. Do I just write "Gasp!"?
There's probably a few more but those are the only ones I've found skimming my notes so far. I'll go through them again and post if I have anymore.
If you want to see the beta version of the novel, it's here. Thanks!
