Looks great, but please consider making the weight less complex (simpler peek-a-boo elements).
To be honest, the translation of the Majapahit logo looks like a 4-point Japanese shuriken and I am not digging it.
A simple etch of the original logo in a similar aged/worn style of the Vitruvian Man on the weight would be classy.
That would also bring the cost down for machining.
