the problem with blockheads is that most human poses don't work due to their short proportions and the implied length of their arms. The best solution is to make the entire model longer.
thats what makes the game feel so casual and cartoonish tho, the exaggerated proportions
i get if you wanna go for more realistic but even so you dont have to go literally real life human body proportions - just less exaggerated would be enough. its a great model but its mildly creepy cause its a clearly-non-human design that has human proportions
plus imagine that thing walking around placing blocks or fighting in a block based env. seems like it would feel a bit out of place being so high fidelity/realistic compared to the blocky simplistic buildings around it, sorta like army men models in blockland running around and building. its not unplayable but it feels weird and out of place
