Thanks a lot everyone
I was not. While I agree the head is not that great, I personally really liked the helmet design I built and essentially built the head around that, with the yellow 2x2 round plate vaguely emulating eyes. While the overall result does look rather abstract, I think it's a worthy sacrifice for the helmet design.
Well you can't throw this moc against a wall and expect it to survive, and while it is undoubtedly more fragile than a "standard" CCBS or technic MOC, The technic/CCBS frame makes it so the moc doesn't fall apart when you mess around with it. And even then, I don't play with my MOC all I do is display them so as long as a MOC can stand upright without falling apart, everything is ok in my book.
