I kinda wanted to make a tutorial on what I've done for http://www.furaffinity.net/view/16113029/ so hopefully y'all find this a bit helpful! If you have any questions feel free to ask. :3

1) Sketch layer, I try to keep it clean as I go so that the inking process is a little bit easier down the road.

2) Inks + Flats. I lower the sketch layer's opacity to around 15-20 percent, then go over with inks, adding extra details as needed. Afterwards, I lay in flats in multiple layers, breaking apart different groups so that I can easily edit them later if needed.

3) Shading. I like to fill this layer to 50% grey, then block in where light/shadows would be. This layer later be set to the Multiplication blending mode, but while I'm working, I leave it as a normal layer so I can get a feel for the overall value of the picture I'm working on.

4) Gradient Map. I think this is a Photoshop exclusive feature (feel free to correct me if I'm wrong!) but I like to add this process to add some extra color and saturation to the shading layer underneath, as shown in the following step. It basically takes the value ranges of your image so far and assigns different colors in your defined gradient to those values, from darkest to lightest, so there's a lot of cool stuff you can do with these! If you're using another program, you can lay in the colors you want, but it takes a bit longer.

5) At this point, I set the layer from step 3 to Multiply mode, and I set the layer from step 4 to Overlay and lower the layer opacity to 15-30 percent, depending on how much extra saturation I want to add in. I use layer clipping with the flats I had laid in, so that they're exclusively shading/saturating those layers.

6) Details. Here, I go around adding small details using various types of layers, usually on top of the main color layers I previously created. And I've added a background, and stroke around the character to make it pop a bit more!
