I really like it man. Everything seems to fit together really well. Though I would say maybe work on smoothing out your shapes some. I mean it fits with these sigs I think but if you do anything else style wise I would try to work on maybe using less blocky shapes. Smooth them out some so its a bit more natural.
I do like this alot though. Nice work. Plus don't make a tut, let them figure it out by them selves.Its not really something you need a tut to do.
