As noted, looks like you pretty much reinvented Ed Shenk's Letort cricket. Shenk himself, at least according to his videos, doesn't actually spin a deer hair head, but rather just tied a deer hair wing a la an elk-hair caddis.

The Letort cricket has a plump black body, a black turkey slip underwing, and a black deer hair overwing/head. The Letort hopper is the same, but uses different coloring.

Just to comment on your tie, it looks as if a) you cut the tips of the elk wing off; and b) left a lot of under fur in the wing. Was the latter intentional for some reason?
