Wooden ring and cup with simple decorated shape carve on body Low-poly 3D model

Nice topology as shown in preview images. Ring and cup was made with loop tools not by modifying default object in Blender, Chinese script and decor shape was engraved to ring and cup body manually. I did not use any modifier or plugins. All images textures were modified by GIMP. Make sure model looks realistic and light enough for animation scene, good for rendering from front view, top view, a bit from side view. Render engine: Eevee

Only quad in model, no N-gons, no triangulates, no vertices with more than 5 edges, UV unwrap manually, no smart UV project, no UV overlapping other standards also meet CGtrader requirement. Please see attached image for verification from Kodama. However, I got problem with UV stretch.

Ring vertices: 9112. Ring Dimension:19.8 x 19.8 x 3 mm Cup vertices: 13594. Cup Dimension: 70 x 70 x 75 mm Cup ( with handle) vertices: 6592. Dimension: 115 x 85 x 80 mm

2K textures: Diffuse, Metalness, Roughness, Normal. Material has not baked into textures maps yet.

Avaiable formats: glb, obj, fbx. FBX file ( no embed textures), image textures are in zip file.

Any question about working process, any idea to improve model quality, please let me know
