Hello, I've seen your Hayam Wuruk and Gajah Mada. I do say, I'm impressed.
But if I may add a few suggestions.
The Kings of Majapahit do have a penchant for tiered crowns, something they supposedly got from the Kings of India (but never a Turban), so I do like the tiered crown you placed on Hayam Wuruk.
However, they don't wear facepaint the kind that the leaderhead has now. What they actually wore was some sort of make up that makes their skin yellowish. Its not gold dust, its turmeric.
If Suryavarman from Khmer did use Gold Dust on his skin, some Majapahit Kings and Queens would probably say that Suryavarman overdid it. But Suryavarman's name does mean 'Sun King' or 'Lord of The Sun' or something close to that if I'm not mistaken.
The toga you have on Hayam Wuruk is great. Dignitaries back then wore that, according to some records.
Now about Gajah Mada.
Loved your Gajah Mada, just a small problem.
I think the hair is too wide on the back. Of course if its too hard to change, don't change it, its fine as it is.
Gajah Mada is supposedly a bit stocky, you already got that right.
The little top on his head is correct for that time period. even commoners have that kind of hair.
His clothing is spot on, so there is nothing much to change.
Gajah Mada is a bit of a warmonger, supposedly during the time of Tribhuwana (Hayam Wuruk's Mother) he had a feud with another noblemen on who would lead the army.
Lets just say Tribhuwana got mad at the both of them and lead the army by herself with the help of her cousin Adityavarman (who later became her Vassal for other territories under Majapahit that were part of Srivijaya)
And another thing which is interesting, Tribhuwana did leave the throne when Gayatri died, but she created a Council (whose members were noblemen) to 'Advise' (or steer) her son Hayam Wuruk while she still held her Duchess title over Kahuripan.
So yeah, for a while for Hayam Wuruk, whatever dear mum said was LAW.
Another interesting note, Gajah Mada came into power due to Tribhuwana and it was her policies that expanded Majapahit's territories. Hayam Wuruk just continued those policies (at least some records indicated that).
Sorry if I seemed to go a bit off topic in the end. Its just so that you'd get the feel of what kind of leaderhead you're making.
Keep up the good work.
