You will think that he is holding the chain of the dog tag between his fingers. But then if you look at the dog tag, you will feel that it is a sketch. So what sorcery has the artist done here? Well actually, the whole of the picture you see has been sketched by him. This is the beauty of 3d sketching and we believe that he has done a good job merging the 3d sketching with the basic two dimensional sketch. Also, a bullet appears to be a complementary object along with the main sketch or did he want it to appear tough?
