New painting prep - tiger and human

Came in today to organize my studio for the crit, bringing out the previous work i had done to show. Using the composition i created in my sketchbook a few weeks ago, i started to draw out an outline of the tiger womens form. I found this quite hard to do, trying to fit the image to the board and then getting the proportaions correct but i am pleases with the outcome. This image is going to show a human/animal stuck between forms, indicating how it has not been finished by evolution, a rejection, a mistake, or perhaps it the human/animal is meant to be like this? My next step is to undercoat the image with acrylic paint again to make areas stand forward more from the board and the colours i am going to use will have that extra brightness/ contrast to them. Over the weekend i need to do a compositional drawing or painting of what the colours will be.
