Tips: Check your Stabilizer. It's on the toolbar on the top and should be to the right. It helps keep your lines smooth. I set mine to 10.

Layers are the most helpful thing ever. Go crazy with them. I usually have at least 15 layers in one complete image.

The magic wand tool is the best. Use it to select only certain areas you want to color.

Play with the "Mode" your layer is set to. The Mode option is on the far left toolbar about where it shows your layers. It is automatically set to Normal. See how Luminosity, Multiply, Overlay, Screen, and Binary Color mode sets affect the picture.

That's about it! :)
