Cute little guys! Nice start, the head you made looks nice. But the mesh is much to dense for this stage of modelling imo… wouldn’t it be easier to model a simple base mesh and then add the details ?
keep it up,
ah, okay, that looks reasonable although the head mesh is quite dense… i wouldn’t use this much loops at this stage… too much loops make it difficult to find the basic shape of the model imo.
i agree with Anthony concerning the ears, they look pretty flat… give them some “thicknes” to make’em look more organic
other than that: very clean mesh an d nice modelling !
