In this stage I added some darks and lightened the background. The edges are starting to emerge but some are still ambiguous. Colors are important but so is value. Don't ask me which is more important because I think they are equally important! There are a lot of artists out there that are Pro Value and others that are Pro Color but I say why not have both? To determine your values squint at your subject. Squinting gets rid of the details and lets you see in bigger chunks making painting easier. You'll look silly but believe me its worth it! Another valuable tool is a value scale. I bet you didn't know that if you squint and put your value scale over it you will find a value at which even the brightest color will match one of the shades of gray on your scale. I hope you understood that last little bit, if its unclear just comment and I'll try to clarify.
