The Horns on the helmet should stay the same, but be thicker.
The curl should be like the ones on Goff's helmet, or like the ones on those sunglasses at the bottom of your page.
I would just thicken the horns.
Now, If it's modification for "depth" purposes only........I keep the HORNS THICKER AND SOLID, just add the shading of yellows and golds to make the horns look more 3 dimensional......No "GRADIENT" for sure, that's a definite mistake!!!!!.......No broken Gold Horn with blue line in it.....Just SOLID YELLOW/GOLD Horns.
