I have found very nice picture of scary dragon,
here it is for example:[link]
so I try to draw it and here can you see finished result. I saw many mistakes in this picture but I'm not sure that I have so much time to fix them because I've some works in progress which I want to finish.
This is my old work, I didn't use someting special to drew that, only normal Koh-I-Noor "Scala" plastic pencils.
