About this 3D model

Another Monster Pet I decided to create. In this one I made it in a single piece with two versions, a Medium Poly and a High poly one since I'm not sure which one is the best for 3d printing. I modelled a support for it aswell, but it is optional, so there is no attachment to join both (glue them together) Any feedback will be very much appreciated. Thanks in advance, Miguel Redondo
