I'm a big fan of illustrated girls. An artist that gets to capture the beauty of the female form catches my attention quite easily, even more when the girl illustrated is Mia from Pulp Fiction, Mystique from X-Men or Amelie Poulain. Ilya Kuvshinov, a Russian artist, really knows his references, and has done some fantastic illustrations showing these girls. Here you can see his work, which I find amazing. His style is pretty awesome, not only his trace, but also the way he "renders" his pieces.
Terrific Sketchbook Works by Pierre-Yves Riveau
Some might consider sketching just a way to improve one's skills, but if you push a little harder, you might get to become a kick-ass sketch artist such as Pierre-Yves, a.k.a. Pez, who makes some fantastic sketch works!
Pez, a French artist, comes up with some truly amazing pieces, using only pencils! So, when you're equipped only with your pencil, there are no excuses for not trying harder! Go further, I'm pretty sure Pierre-Yves would tell you the same. These are only some of his pieces... for more of them, please visit his personal page and his Behance portfolio. Also, if you got your own sketches, share it with usI hope you enjoy these! Cheers! ;)
