Not sure if......

     I've started the digital illustration for my final project and this is the first illustration. To tell the truth, I have no idea if I am doing this right since.... well it look odd to me. I have no idea how to do the digital illustration actually. So I've been referring to illustration book. might as well said this is my first try since before this I'm just playing and messing around with the tablet. Any advice?

Yes, it's not complete yet. And... please don't mind the plain background. I am planning to replace it anyway.
