The eyes and the spiked bucket are the parts that I recognize ;), the rest matches with your description but it is not something my eyes understand ;)
Now that you mention it, it is kind of hard to read at certain areas.
Anyways, it's just a dark ghost with flowing blue hair, decked with a fancy clay headgear with some orange crystals, who is inside an iron, spiked bucket. Its eyes and mouth are glowing in case your wondering.
It is a bit hard to read.. I wanted to ask a smart question but I don't even know how to describe the parts that I do not understand ;)
I like this, it looks awesome! the blue body and the crystals are very well done and I like that menacing face!
