Hey there!
Yup Imma huge fan of Full Metal Alchemist and this while it wasn't intended to be some fan art or related at all with it...it seems to have to many references to it, just like at it an Ouroboros, a pocket watch and Philisopher's Stone... hehehe, however this is intented for a backcover of a book, just a sketch for a eventual cleaned up and final version done in vectors.
Technical Info:
Done with Adobe Photoshop CC 2015
