Quick, rough lines for ya. perfectly tweakable (i cant use the onsite program, my OS doesnt support)
I couldnt tell if those were spikes or fur.. so you got fur. If you could give me some direction on what your final product should look like, it will be easier to tweak these lines to look better for ya (i resisted the urge to change your lines too much.. the head isnt looking quite right, but you probably dont want the heads i tend to do

)
Its probably not quite what you are looking for, but if you can use, awesome. Lemmie know if you need it colored or anything. I have free time off and on during the day to work on it. I'll probably be poking at it either way, some of my lines are bugging me.
