Constructive Criticism on my foam base?

Hey guys :3
This is my furst post on here, so I hope it doesn't stuff up xD

I'm currently working on my second fursuit head, and I'm doing my foaming stage, at the moment.
I would just really appreciate some constructive criticism on it, due to the fact that I hate how it looks, so far.
I've tried rounding it off /so/ much, and it still looks blocky, and I don't know why. This was the same case for my furst head, as well. Does anybody know what I'm doing wrong?
And I can't seem to add a top piece of foam, on his head, because it just crinkles up and doesn't go around the head. And even if I do it in segments, there are just large gaps everywhere. So I'm not sure what I'm doing wrong.
This is what it looks like, so far~



Note: The ears, nose and mohawk aren't the real deal, at the moment. I just pinned them there, so it didn't look like a duck, for the photo, lol xD

Thanks, in advance!! :D
