I love sound in real life, also a musician so try to incorporate them as often as I could in comic form.
The other challenge was to make the text not take away from the CGI visuals but be clear enough for the viewer, it's something I continue to experiment with in each new episode.
My fave so far was listening to a car alarm to imitate the variations they play. The car alarm blasts through the entire fight scene after the collapse of a heavy creature.
The comic plays off like an action horror console game so if your a gamer this one might be familiar
It's a comic where a handful of people including heroes are asymptomatic carriers of a virus that turns others into feral monsters, so the indication sound of their transformation is "Chrk, Chrk"
-as the infected person's necks twist and they choke up
In the recent chapter, I started including Music SFX - and additional inserts for people who can read music. The melody the character hums was from an old song I had wrote
Bonus:
This was from my 1st attempt at a comic I did years ago based on my home Country Trinidad, "Blaw" people used say back in the day "he hit the guy Blaw" haven't heard anyone used that word in ages so it prolly died out XD
