Looks cool. I like the Jansen X wing helmet design!
My only critique would be the hand painted black lines. Use masking tape for those to make them cleaner. Or if you paint on the raw white styrene, you can actually scrape away imperfections. I am not a great painter and tend to hide my 'mistakes' with weathering.
I love aph helmets. I keep hoping to acquire one. Post up a show off pic of your aph next to the x wing one!
