Please make the legs of metal gear rex

Could someone please make the legs of metal gear REX?

I’m new to blender and can’t figure out how to fine-detail objects.

Here are two screenshots of it for reference, as well as the foot that I made.

No textures needed, just the mesh.

Keep at it- I tend to model as separate volumes and then do a boolean and clean up.



Thanks you!
