3D Kangaroo Mascot

We want to create a 3D mascot which we can then setup in different poses so that we can create Jpg's to insert in various artwork. The 3D mascot is a kangaroo. I have attached a jpg showing the style of the kangaroo which we want to create. We are not looking at the different poses just yet as we want to get the 3D model sorted. We need this kangaroo in full view. It will be used on printed artwork so the quality of the kangaroo needs to be sharp as well as being able to create large jpg versions as well. Vector formats would be preferred if possible. Once we have the 3D model approved we will then look at the various poses. These poses may include props that the character will hold/wear etc. No background props will be required. The total number of poses at this stage will be 4.
