The villains in my story are large reptilian creatures. Nine foot tall, some with wings, some with spikes or horns. They do not have much dialogue in my story, just a few bits here and there... But for the dialogue they do have would it be hard on the reader if I stretched certain letters? For example: “Generrral, rrreconnaisssance confirrrmsss thessse arrre the rrremaining Atlansss,” grunts his aid. “Prrreparrre my yacht, I will inssspect the fleet perrrsssonally,” orders Dokrerk. I was planning on just extending "R's" and "S's"... Or is that too much?
