Bind Runes?

These look like Runes or maybe Bind Runes? I'll have to do some investigating.

Tattoo

One of my nephews asked if I could draw a tattoo combining two runes, the Aegishjalmur and Othala runes, for him (he's got a Viking theme tattoo thing going on). I played with a couple of different ideas, and he liked this one. The top image is a pencil sketch, and the lower is a very rough shaded sketch as a suggestion of a grey scale shading.  Now for the ink version, which I think I'm going stipple shade.
