Ok, so you figured out the problem yourself: Your color schemes is WAY too dark. no points of interest, nothing that catches the eye except the feather charm, shields blend in too.
As a general rule you should pick like 3 spots/sections of your model that "look interesting" make them "pop" you know. I used a very similar scheme for my skinks.

so what happened here? I too used dark colors to set off the face, hands and feet. But to make this work they have to contrast the rest of the skin. Dark war paint needs light skin colors or it will just look dark or just light--> not interesting
As for my first point of interest I chose a vibrant yellow to make their headfane? and eyes pop, help to bridge the 2 different skin colors and draws attention to the head of the model (head,chest, exposed back, weapons usually are good points of attention)
Second I chose the shield, contrasting it with red to blue skin gives a whole unit of this some distraction from the ever blue skin.
Instead of the weapon (quite muted green) I highlighted the scales on the back pretty bright just to set the skin further apart from the warpaint.
So what can you do? If you want to keep the dark skin color go with a bright warpaint (white or a bright yellow eg.) Dont make the shields fit the model, set them apart. Doesnt have to be some bright color like mine, just dont go blue or green like the skin.
If you wanna keep the dark war paint choose a brighter skin color. Washing an already dark color like Kabalite green with a Contrast paint will severyl darken it down. And you chose a pretty dark contrast paint too. I painted the whole skin of mine with thinned down terradoen torquise!
