I started by blocking in the local colors as you can see in the image at the top. I've been working on color composition and lighting effects in the other one. The piece still needs a lot of work in those areas.
So far my major concerns are still with the brushwork. I'm going to try the overlay and other types of layers tomorrow to see if that achieves the effect I want. I will probably try switching to a different brush as well.
I'm also not satisfied with the bolts of lightning so far. they seem to be overpowering the image to much, so I'm going to try to rework that tomorrow also.
