[Argh][WIP] I can never seem to finish a Twilight drawing.

I have done about 15 sketches for Twilight, and started to color in three of them. [This is the only one I actually want to finish] (http://i.imgur.com/q0muk.png), I just don't really know about the hill and the shading. I have come up with a few ways to change her base colors to work with the moonlight, and I think I finally found a way that works but I will keep playing with it. Started this yesterday, haven't really got a chance to work with it today I also planned on doing this whole piece without an outline, except the undersketch.

The other drawing I have lost all interest in. [Here is the first of the two] (http://i.imgur.com/3q1s7.png) and [here is the second] (http://i.imgur.com/7whzi.jpg). I did these over the past couple days and they just did click for me. I didn't really enjoy the scene I was drawing. Also drawing books I didn't really care for.

Also to everyone at the meet up I hope you are having fun. Now back to work for me.
