My first digital art - update

Its the same art as the first one I uploaded, but with more ditails and stuff.
I have been working on it for a long time (too long if ask me). But i not used to the tablet or the progam so i am working realy slow. To be honest, I dont realy know what I am doing. I am just trying out stuff.
Anyway I would like a opinion on it.
Pls let me know what you think.
