I think it is a good first digital picture, too! You definitely do understand the basics of coloring and shading, as shown on her dress and cheeks. I think once you get the hang of making smooth blends, it will come second nature to you, although I cannot understand how difficult that must be when using a mouse! Yikes! You’ve done a lot better than I would have!
This is great work, especially considering the fact that it’s your first piece of digital artwork. The depth in this piece is quite nice, especially the blurred background.
I might recommend blending the character in a little more with her environment. For example, fire tends to be a pretty bright light source, so you could paint some stronger yellow-orange highlights on the parts of her that the fire illuminates. It may also help to use dark brown for the shadows, so she blends a bit more with the background.
Nonetheless, I think this is a great picture and an excellent start!
