In my last post I gave a preview of this month’s painting describing a situation we’ve all been in before: You’re making your way down to the grocery store for pop tarts and there’s a some dragon blocking the pass.  
Today I will be going through a few of the development stages for this painting so you will hopefully get a feel for how you might get around something like that.
Line Drawing
The 16″ x 20″ drawing was done on reliable Strathmore 500 vellum bristol. Still one of my very favorite papers to watercolor on. It’s only flaws:  it is too nice to people, and works too hard while on the job. 
Digital Color Comp 
My color comp is fairly saturated here, and laughably ambitious for a watercolor on bristol. I may want to get this saturated in watercolor, but I’m not an actual wizard. I’m just an average guy who won a wand and pointy hat in a game of No Limit Texas Hold ‘Em once while running guns in Peru. I know good and well that when it comes to it I likely won’t hit this kind of saturation in watercolor, so here I am mainly planning around my final digital image.  
While I am working in watercolor I will print out a black and white version of this color comp to use as a general value guide. I will revisit this color comp when I scan the final image in. 

Finished Watercolor detailed in Acryla-Gouache
After finishing the watercolor itself I lay in opaque passages and highlights using Holbien Acryla-Gouache, which blends really well with watercolor. It offers the smoothness of gouache, but the permanence of acrylic. You can see in the images above how much of the detail and dimensionality the Acryla-gouache pass brings to the image. 
I will say that this product is noticeably less smooth than gouache and watercolor alone, but I find that I have an easier time controlling it than I do gouache. It works well for what I need it to do.  
The image below shows the stages of the painting: 
  1. The order of events: 
  2. Drawing in Caran D”Ache Pablo Pencils
  3. Watercolor and Acryla-gouache
  4. (Photoshop) Multiply and Soft Light Layers
  5. (Photoshop) Color Dodge layers 
  6. (Photoshop) Screen layers with saturated colors
  7. (Photoshop) Opaque Normal layers

There isn’t a great deal that changes from the watercolor to the digital final. It is mostly that the values and colors are punched up and sharp details refined.  (However, this last part is hard for me to overstate. I have the approximate vision of a mole rat or a very deep sea-dwelling creature. Being able to zoom in close to the image means that I can finally give these details the treatment they deserve.) 
The bulk of the time is spent working on highly transparent layers to bring more vitality and dimensional heft to the image.
