What is the file format of the characters? Would they be fine in threeJS?
EDIT: Just read the description properly and they're blender files. Excellent
I have made a tool that can scale the mesh based on the weights of the joint. So select the joint and scale it up or down. It can also combine multiple animations of the same model in to 1 model, edit animations frame by frame.
This GIF shows a zombie character using this model with changed dimensions 
Meshy is bloody awesome! Its disappointing to see that the game jams dont allow for AI generated content. I think this AI hate is similar to drug dealers voting against legalization of drugs just because it steps on their toes.
I think you would be paying in the thousands to get those models made by someone. Let alone rigging the models etc.

if the link works for you, I am working on an open world space game. Still in very early stages, but the planet generator has already come in very handy for the planets in the overworld. The planets have a gravity pull to make the travel around the overworld more interesting
Thank you for your input. I am just starting out getting in to pixel art as it was the one thing holding me back from my dream of creating a video game throughout the past 20 years, just never had the skill or patience until now lol. I think I understand what you're saying and I appreciate the constructive criticism. I will take that on board and look at more examples to evolve my abilities!
Maybe the updated one is more to your taste? https://synkrowngames.itch.io/bobby-character-and-tileset
Still a little dull but I think it looks way better
