how to fix this foam base?

so at first, hey ya'all.
i'm currently making a fursuit head in a rush - i must finish it before wednesday. the only problem is that the only avaible material at the moment was foam - and i'm bad at working with it... that's my third head, first was plastic mesh and foam and it came out really bad, second was resin base and i was happy with it.
the main thing is that something is off about this base. also i'm out of bigger pieces of foam, just scraps left, so i can't remake it or make some really big fixes...






(lol, that last pic is scary)
i know the eyes are bit failed too, but i have no craft foam left also and i can't remake them. the nose is just a placeholder, it doesn't fit at all and seems to small.
he's going to be a generic, natural coloured wolf.
