This is my personal work space. It's nothing very fancy, but it's suited me quite well. I've kept the right side as empty as possible, as I've found it easier to keep a good workflow when I have as much room as possible to see all my layers and materials. On the other hand, the left side is mostly focused on the things you'll need in order to actually draw, as I find it easier to quickly switch between colors/brushes/etc. from there.
(Note that the thumbnail is stretched to accomodate the asset store's image requirements; the image below is a more accurate representation of what it will look like when it's imported.)
Hope you enjoy!
