Much like writing, art is a process. In my experience, they're actually really similar processes (does anyone else feel like the plural of that word should be "proces" with a long "e" sound is it that just me?). Now, I'm sure you could draw a few parallels between the two yourselves, but let me explain my own reasoning.
Both things start with an idea. Either you're asked to make something based on a specific prompt or you suddenly think of something that sounds really cool and want to make it a reality.
After the initial spark, I sit down and think about what I'm about to create. I try out a few things, decide what works, then go into some more in-depth planning: an outline. A book outline is of course a rough sketch of the plot, maybe a few important lines you want to include.
I know that some people don't make an outline when they draw; I also know it's a lot more difficult to do when it's not digital art, too. God, I love being able to erase things completely. But anyway yeah, I start with outlines. I'm making my own cover art for my contest entry, here's the outline:

I usually do my outlines in hot pink so it's easy to tell when I'm leaving white space; hot pink stands out pretty well in most cases. I map out the shapes of every element in the photo and also where I think the shadows and highlights should go.
Then after the outline, both art and stories have to be fleshed out. You have to put the color in them, the meat. This is my favorite part because it's so relaxing and it's fun to see everything come together.
Then, the next step is the details. Proofreading, evening out line weights, adding some missing shading, rewording sentences to be as perfect as you're capable of making.
After that, there remains one final step: putting your work out there and immediately seeing seven things that need improved, despite having looked at it with a meticulous, scrutinizing eye for multiple hours or sometimes days. Never fails.
How does your writing/drawing process differentiate from mine? Do you have interests beside writing that you find similar even though on the surface they're incredibly different?
