I've recently bought a couple of copics and have found myself in love. But, I don't think I'm using the few that I have right. How do YOU use copics? Share pictures? One of mine is the picture attached, the greys and skin are copic.

I recently won a set of copic markers, it was the 'ciao 72 A' range so it's quite good. I myself am not very good at the moment, but from what I've seen, it's all about the shading. For the shading on your grey jumper, try using either a colourless pen to smoothen the light grey and dark grey so it's a nicer gradient or you can do the opposite, which is making defined lines where the highlights and shadows should be.
With the face, make the outside of the face darker by using the same colour on it again. This creates a more 3d effect. And for the hair, make the middle lighter. You can't on this one, but when you start a new one, bring the pen from the outside in. Example in the picture :)

...So you see the middle of each clump of hair has hardly any colour on it. Have a go at that. Good luck! ^-^

Thanks! Will do! :3
