It looks awesome... Is this done by ball pens and marker? and the color by crayons? Well, another question.. some one told me that..when you make shade by pencil..you shouldn't smooth them out! Is that true?
the problem with smoothing out pencil is that sometimes you get a weird plastic look from it if you crosshatch in a good way you can get a really nice feel
here it's not nice at all, it's just a simple sketch, wanted to get the idea on paper so that I wouldn't forget it but you should also adapt to your medium - for instance with ink or ballpen you crosshatch in a certain way - you can only draw lines of certain width, with pencil maybe in a slightly different way, charcoal different again, pastel etc. and even within these media you can use different styles - fill the object with crosshatching or just infer a bit the volume from a few strokes
the crosshatching is still too... "crossed" and doesn't shade properly to push forward the shape google crosshatching (images) or search on youtube for tutorials it will help you see the process - I'm not very good at it either
