Like I said in other topic, I don't know who created the idea first, but whoever did gets major points. Either way, regardless of who created them, I like your sketches the most, they give them that Blockland feel and it seems to fit well. I don't like the actual model though, it seems too small. It needs more expressive legs like your drawings have, I'm sure you didn't make the model though, but this is just a heads up to who is making it.
Good work
