3D Character Model Refinement

I'm seeking a skilled 3D designer to correct an existing character model. The original design was created in SketchUp and needs several key improvements.

The corrections required include:
- Shape modification
- Texture improvement
- Dimensional accuracy

Ideal candidates should have:
- Proficiency in SketchUp
- Strong background in character modeling
- Expertise in texture and dimension refinement

Please provide examples of previous character models and relevant experience.
