That alone won't, but if someone irl suspects they know who you are your silhouette can be used to verify/confirm.

I wouldn't, just to be on the safe side.

Why would that be the case?

If even doing the traditional equivalent was as bad as the basis of this question implies it may be, then one could say I may have kinda taken the misstep.

Eeh, i dont think anybody will be able to find you based on that. I myself have as pfp a drawing a friend of mine made, and its been fine

Well it's tracing so presumably the outline would be very similar to the real outline and you'd be recognisable.
