Contrast draws the viewer's eye. That said, there are many different ways to achieve that contrast. You can use value, hue or temperature, or a combination of all three. Value contrast is the strongest worker of the lot, that is why I will check my paintings in photoshop. I simply change the mode to gray scale and I have a tonal check-up. If it looks good there, then I analyze the color.
This painting has gone through so many metamorphoses, finally making it to this. I know the contrast is not super high, but I hope I made it enough to attract the eye of the viewer. I think that there is the reduction of shape, vibration and sense of wanting to know more.
Maybe its next metamorphosis will be growing big. I can see this one 60x60.
It's snowing like crazy outside (yay!)...time to do some snow study.
