Skull and flowers

Ok, I dare you to fing my signature in this piece.. It's not really good, the thing I like the most are the flowers, since the skull is not anatomically correct, 'cause I made it without a model or picture, so I kinda bluffed a bit, since I was in class and all that.. And it didn't went well at all.. But I like how the two images look together... All ball pen and non edited..
Hope you like it
Have a nice day
PD: Tell me what you think, but keep in mind that I already know that the skull is not anatomically correct
