Those of us who like painting are often in search of a software tool that resembles the texture and feeling of real painting on a computer's screen.
Greenfish Painter is an attempt at obtaining that sensation, but unfortunately it falls short of expectations especially when compared to other painting tools such as Artrage or TwistedBrush.
With Greenfish Painter you can freely paint on white canvas, obtaining a texture that's similar to that of real paint. Plus, you can mix several colors on your brush and create a really attractive mixture.
The brush can be tweaked in many ways (size, roundess, angle and more) but sometimes it's too slow - meaning that the painting appears a few seconds after you move the mouse.
On the downside, the program's interface makes brush and color picking a bit difficult: brushes are loaded as presets and colors must be chosen inside another menu and not on a paletter as it would be desirable.
