This looks great Graishak!
The skeletons look great, especially their shields, and I like what you did for the main base.

I do agree with StToad and Ekipage: the skeletons have different "base texture" than the large base.
If you feel strongly about it, maybe scatter some of the same gravel onto the skeleton bases to blend them in.
But I don't think you have to, they look great as-is!
