Hi,
I have seen your attached Animation and will sure to do 20-second animation in Maya as per your requirements, I assure you that my created Animation will be Elegant, Eye-catchy, and realistic made on high polynodes that will help your Animation to stand out with others, I will provide you multiple rounds of revisions.
I am experience 3D modelers and Animator with 10+ experience over 3D modeling, Skinning, Rigging, Rendering, animation and etc, I always create virtual worlds and objects, typically done by breathing life into sketches and concept arts. Looking forward to doing the same for you.
Please have a Look at my past 3D modeling work:
