I also think it will catch fish, so no need to use the tool I usually have close at hand when trying a new pattern -- a razor blade to salvage the hook.

I have to tie a lot of tiny flies out here, with a #18 hook being a fairly large one for me. Coming from this direction, a couple of tips that may help:

(1) Dub your thread very sparsely. That way you can build your body with multiple wraps if needed, rather than being forced into a large body with a single wrap.

(2)Experiment with using a Matarelli whipping tool to build your heads. It gives lots of control and the fly is complete whenever you have reached the head size you want
