Hello,
nice build !
My tip concerning antennas:
Try toi find piano wires, that's almost the same item that what is put on hasegawa kits and even better, because i find hasegawa antennas a little bit to thick.
piano wire is strong but relatively soft (that could be twisted) and very cheap.
I used some in 1/43 scale, heated sprue being too weak (or doesn't keep straight line and only give twisted antennas when it shoudn't !)
