Yeah thanks, I could use all the help I need. I do plan to start learning but I really want this werewolf costume. Hopefully it'll teach my for further projects.
However I mainly want advice of how to make the head of the first werewolf if you could help me on that.
Sure, no worries.
Well, if you look at the link I posted before you can get a head blank ready made, of course there are other people who make and sell them too - a search for "werewolf head blank" or "wolf head blank" should get you some results and you can check out the shapes you like. Even if you don't want to buy one, they'll give you a good reference point for making your own.
As for the actual construction, it depends on whether or not you want to purchase a headframe. If you do, then it's just a matter of making an EVA foam or elastic backing so it sits comfortably on your head, then building on any extra details using upholstery foam (filling out the back of the head, making ear forms, adding snarl folds, that kind of thing), adding eyes and eye ports, adding fur and then detailing by shaving it down and drybrushing or airbrushing in detail.
If you're not using a head blank, you need to build one. I do mine using foam as I said - basically the same method I used for my Space Pope (
construction pics here) - an EVA foam "helmet" built to fit your head shape comfortably, an angled strap underneath your chin to support the jaw movement (for longer jaws you need to supplement this with elastic and a light, rigid support structure to get rigidity and full jaw closure) and then you carve foam features to build on it. IT takes a lot more playing around with the forms than starting on a premade base and a lot of design and referencing to make it look cool, but you do get a lot more flexibility in the design.
Edit: Forgot a really important thing - make sure you figure out the overall shape and proportions -before- you start. Nothing worse than making your head to find out it's too huge and makes you look like a grapefruit on a toothpick! Best to start with photos of yourself and sketch over them to find a shape you're happy with, I just threw this one together in case you need an idea of what you can do.
