My question is why do you want to make it with foam...? if you really want to make it with foam try memory foam the ones we use for beds.... and pour in some viscous latex on it. If you really want to make a predator head try sculpting, it is cheap and it makes a better result than foam. To be honest no the head you made does not look like predator. I would be a liar and a no good teacher if I tell you ''Yeah continue that way...'' Personnaly i never sculpted before and my predator head was my first sculpt and i made that result
