Beautiful.

If this really is a self-portrait, then I must say, you look very beautiful. The detail and shading for the hair and face are extremely good (it's almost like their glowing). My only criticism would be the spot right below the rib cage; it looks like it comes to a point at the bottom where as the rest of the area above encompassed by the rib cage is smooth without any trace or slight indent of rib, like only the lung is there. I hope I explained that well enough. I don't know a whole lot about anatomy in drawing, but I just wanted to give my opinion. Good job on the drawing and good luck with your future ones.

Beautiful, smooth, gorgeous. Looks like there is a lot of horsepower. :)

Can I hace this? :D absolutely beautiful.

Whoa, mostly pencils? That is insane! The flames are done nicely, and the engine has a lot of detail it in. Very impress on how you did the hair and eyebrows. Like how you got the eyes to feel like their holding you in place as well.

And if this is you, whoa, go you! XD But really, this is nicely done!
