Unicorn gundam Phenex Horn / Antenna

an amateur recreation of the horn/antenna that would be on a unicorn gundam phenex. The size might not be right as I didn't make sure to size up everything to the proper proportion. no etching or detailing too cause I have no damn clue how to do this. the horn is also completely flat, no increased column or anything like that, sorry.
honestly, if anyone can use this and make a better version, please do, and also send me a copy too. Thank you.

I used the shape of the horn that was already on this model. i (somehow) managed to detach it and then add the connection part on to it
