Copic Practice

Just had the urge to practice with my copics..well, the remaining ones. Unfortunately the shop where I used to got them, stopped selling these so I'm currently confronting the decision whether to use the ones I already have until their empty or whether I will get new ones online..
However, I'm quite satisfied how this one turned out (ignoring the HUUUGE anatomical mistakes. I'm accoustomed to draw men. D: ). However, noticed that I'm missing a lot of colors in order to color satisfactory skin coloration. This one looks still odd to me.
