S'retty good. Doesn't look like Yoko much aside from the outfit and "talent" but that could just be your style/on purpose. I'm a fan of pencil works and pencil shading and your work on the shorts and sleeves is real nice. The short too, though While we're down there that mound looks more like a package. Maybe a lil too buff in the muff. Also like I see shedra say, despite your great shading on the rest of the body the face, especially the cheeks and jaw/chin/mouth area do look a bit flat.
nice picture, though the arm sizes seem a little off for each side, maybe its the angle of the hips..but otherwise very cool ^^ Give Tengen Toppa Gurren Laggan a go and don't listen to the fools here that say the second half isn't worth watching the show actually AMPS up something epic after the 7th ep and it gets Bigger and BIGGER AND BIGGER sorry im rambling but its quite possibly greatest anime of recent years (watch in japanese)
