i like you 3D modelling and i like the squirtle face kinda cute but he modelling at the back of your squirtle not looking circle but this is your practicei kinda like including the face of it. Good joband make it proud!
It looks pretty good for a low poly model, I’d say rework the eyes or make the eyes a decal so it looks more cartoon styled like the Pokemon anime. Also rework the head to be more of a sphere shape and I think you forgot to add a tail like @ekuz0diaa said lol.
