On Pompmaker's concept, I honestly dislike the visible rounds on the joints. I feel like having the character model look blatantly like a toy kind of reduces the diversity of options for what you can do with the game, since with how Blockland's player model is you can portray it as "blockheads are toys" or "blockheads are people" easily, while making the model look like an action figure kind of limits it to the characters being action figures.
Sorry if this is a little hard to follow.
