An Interesting Waste of Time
And I know how to waste time.
A wonderful little drawing system that resembles much of the tablet drawing systems used on sites like Deviantart or even with Corel or Adobe Photoshop, but unlike those, this is available on most computers, And you do not have to be inundated with annoying DeviantArt folks.
In all seriousness, this is a wonderful little system you have rigged up here, I could do quite a bit with the brushes given and, if one knows the intricate and delicate brushstrokes of what each tool needs, you can make a wide array of beautiful scenes.
...And penises. Lots, and lots of penis trees. But I digress.
Well done, your hard work shows through on this successful drawing system. Well done.
