A precious symbol

Please don't come down on me very hard. This is my very first time that I have ever drawn anything from any show much less submitted it online. It is also the first time I have ever tried my hand at shading. This picture depicts Hiei and Yukina's sibling relationship which I totally adore. In fact, my sister (we 'adopted' each other) is 4myownreasons. Her work is also on here along with another best friend's work Shizu_chan. I really would appreciate if you would take a look at their work and leave them feedback because they deserve it! And if you would like to leave me feedback too, well, that's fine with me. I appologize if you don't like it or think it is smeared or whatever. I apologize because, as the saying goes, there is a first time for everything!!! :)
