^^ I agree, the first one was pretty ok. I think you could have gotten more precise though, for some reason it seems clunky to me :/ 5/10
The second one I didn't care for so much. I like how you grab your own leg (this is something that no one really does, yet is full of possibility) and the first DM or two are ok, but after that it degenerates into a rather messy bit of you struggling to get the head off, but it never happens. 3/10
These are both really good starting points though, I suggest playing around with either these openers, or similar ones, and seeing where it takes you.
