Concept visualization sketching

Over the last week, I've been developing my visual concepting style. It started with a request to draw some diagrams for a presentation and upcoming book. The email came from someone who had kept me in their files for 15 years(!) after seeing my GTD Advanced Workflow diagram. 

We started working together on his project, and during a conference call a week ago I did some live sketching on my shared screen. The quick scribbles worked well to help clarify our thinking, but I realized my concept sketching skills were rusty. They wouldn't cut it for any formal presentation. 

I dug into my library, revisited Mike Rohde's Sketchnotes, and took a free short video course from Visual Strategy Facilitator Holger Nils Pohl - thanks guys!

I practiced a bit, and a week later I'm much happier with my sketching. Lots more work ahead, but I'm over the hump. I've figured out a process, a couple simple tools that work (Google Keep and Autodesk Sketchbook), and I'm building a daily sketching habit. It feels good to regularly draw again. 

Below is a progression over the last week. I can only show a small part of the original conference call sketch because it's still unpublished proprietary information. The rest include a live sketch I captured during an online Dungeons & Dragons session with my son, a congratulations for a productivity expert's new grandson, and a Halloween birthday gift for my brother David.
