These are all looking awesome.
I've tried my hand at Mr. Dent a few times. This one is from The Dark Knight Rises midnight showing near me. Makeup and liquid latex only, and done kind of in a hurry.
Second one is from Wizard World Chicago this year. For those wondering about the teeth, I used some press-on nails that I trimmed into teeth shapes. This one was a bit more complex, base of liquid latex, painted half a bald cap, scar wax for the open part of the mouth, the teeth, and red puff paint for the tendons. I wasn't 100% satisfied with how it turned out. (The mouth is going to be smaller next time, and I want something a bit more solid than half a bald cap.) But not a bad first try for the process, I think.
