- Awesome Art: The webcomic's creator is a professional artist, and her skill in both art and page composition show in the work.
- Germans Love David Hasselhoff: Sigeel noticed that Blood Stain rose to top ten in popularity very quickly on the Russian site Top A-Comics
. - Shipping: If the comments are any indication, Dr. Stein and Elliot are often shipped together. For Valentine's Day 2014, Sigeel drew a non-canon Ship Tease image of the ship.
