Nice job. I'd recommend spending a little more time blending, but this would be fine as a sketch. Also, watch the saturation and brightness on the red handle. I'd desaturate it a little and give it some more contrast. Good work, though. Keep on posting!
The Dodge and Burn tools have their uses, but they really don't allow the complexities of colors that are often necessary. Photoshop doesn't "know" about the lighting in a painting, and so the results of using the Dodge and Burn tools often look weird.
I'm currently working on a flower to post here. Don't know what it's called, but it has interesting colors and form. So far all I have is some color swatches...but they're the colors I'm looking for.
