If I could translate Ik what you are saying but there is a simpler way of putting it. The theme of a unicorn works and could work quite well. However it looks more like an excaliber helm since there is an already established concept which consists of horn and sleek simplistic look, thus making it harder to use such a concept. But lets say excaliber never existed and therefore wasn't an established concept. You putting a helm with several pointed sharp edges on it when oberon litterally has not a one well-defined edge. Thus making it look like he invested in a head transplant.

Honestly not that many changes maybe get rid of some of the dumb spikes curve the horn and kinda curve the metal more inward in certain areas. Or...redo the whole thing but, ofc that would change the look tho. I'm not being facetious either I would enjoy a v2 of this considering it did look a little more erratic.

(The reason this is btw is almost all modeling software is a pain in the ass not to use flatter surfaces, unless it works like clay then your solid)

There is actually no rule that "horn" is something exclusive to Excalibur and there's also no rule that every single design traits needs to be exactly the same. I aim for the right balance of similar but not repetitive and different but not out of place. Same thing can be used to play different thing and different thing can be used to play the same thing. Might sounds nonsensical but it works out pretty fine so far.

but oberon its a NATURE warframe his two normal helmets are something about nature and i also think this is a helmet that doesnt match with Oberon maybe excalibur or rhino .im not telling the hel its bad i thinks its awesome but no for oberon
