These are some of the first set of water colors we had to do. My favorite were my keys and my Cherrios box.

I liked the keys because they were kind of transparent yet you could still see the details in them. They also reflect the color off of the green id holder, but you can still tell that there are different color keys, silver and golden/bronze. I did a wash over the whole paper and then once that dried went back in and added details to the keys and id holder. I tried to show that the keys were reflective and reflecting the green. Some of the shadows are done in a gree tone. The Cherrio's box, which you have so I cant show a picture of, that I did I like because it really looks like the box. I did a wash for the background color and then waited for it to dry and then did some wet on dry techniques. For the keys I also did a wash and some wet on dry technique. Since I dont have a picture of the Cherrio's box I thought I would put up another picture for you. It is a picture of my sunglasses, and it remindes me of dsp. I tried to show different reflections in lens' and black arms. I was also trying to make the shadows look like shadows, somewhat transparent, and also show the multiple shadows that it had, which I learned from dsp. I did a wash for the background and then waited for it to dry and did some wet on dry for all the details. (P.S. I forgot my sunglasses, so for now you'll have to live with only one picture)
