Outside a company cafeteria someone left this cup of water which produced interesting light refraction in a late afternoon.

I created the vector graphics in Ai Draw, export to Pr for layer editing (Ai should also do but looks like my Draw app sends the .ai file to the Ai program on my company computer while I was at home), and import to Ch for facial tracking and performance.
The mouth tracking and animation need some investigation.

Fur shading + texturing exercise

A little mouse got trapped a few days ago in the garage.
This is relative easy to draw, as I can easily double the strokes for (fur) texturing and shading.

Bright side down

I sketched the same sculpture I visited a week ago from a different angle.
It started well, but went downhill as I drew more.
When darkness fell, I realized that I probably made a fundamental mistake; I will verify my hypothesis in my next visit.

After the summer heat and before the winter rain, autumn is a good season to spend weekend evenings at the Stanford Rodin garden.
His dark bronze sculptures are hard to draw though; I had a great deal of difficulty with the eye sockets for this one.

Finger + pencil sketching

In this series of quick exercises, I finger-sketched on my moto x4 of what I saw on the BART trains/stations, and penciled over on my iPad the next day.
For some reason, the files are separated for Android and iOS, even though they all have the same sizes (large portrait photo) and present on my creative cloud.

Train sketcher

After settling down across the aisle this passenger asked me if the train is heading to San Francisco. Soon afterwards he took out several drawing pencils, all short likely due to usage, and started to finish some drawings on a sketchbook. With intense focus he crouched over his work without noticing me sketching him.

Illustrator leaves tile

This is an exercise to help me experience the process of creating repetitive element patterns and tiles.
Basically, I can draw one element, and copy/paste it with different positions/orientations for an initial pattern.
I can then create a grid pattern from the entire selection, fine tune the elements with the handy interactive preview, add the pattern to the swatches, and use the pattern to fill a new rectangle (with the same size as the original pattern).
I can then test it via various tiling tools, such as html or this pattern checker.

During the pattern creation stage I somehow altered the aspect ratio away from the initial square, so the result is a rectangle. I plan to fix this in my next exercise.
