And you said this is a quick pencil drawing?! Wow! This is really amazing work you've made! The hair, the skin, the clothes, the shadings are amazing!I've browsed your gallery, you drawn some nice mangas too. I think you're so talented. Great!
Total coolness! I like the composition with the figure filling the page at an interesting twisting angle. Your proportions look good, and you did a fine job on the foreshortening. In particular, the models left elbow on the right side of the picture plane comes forward right at the viewer. I like your style of mark making because it gives a lot of life and energy to the piece. You have a great range of values here with plenty of contrast. And good use of value changes to show the planes and contours of the face, hair, and blouse. It's a beautiful piece of work!
My quick drawings/sketches look better than my finished ones if you ask me.. xD I did plenty of them for my portfolio or now in the university but I don't really like them all. You'd be disappointed if you see them xD Anyway, Thank you <3
