FMA Tattoo Design

My brother wants a FMA tattoo, he found a humunculous emblem with the cross inside, but in my oppinion the cross was waaay too small and a waste of time, so I did some modification to it
all drawn from scratch in photoshop (couldnt find clean enough images to manip)
I'll be sure to upload a pic after he's had it done
