thanks fer the suggestions, all! unfortunately, i finished this and it was crap so I wrecked it. Krayjax isn;t that great anymore. instead, my self-moc is now Tarakona! check him out for some better stuffs!
I'd try scaling it down because the head you chose seems to be a bit too small. Also, the clash of textures does distract from the nice shaping you got. Keep working at it and I am sure you'd improve it!
