3. Now you tinker around with the gradients till you're happy with the general color, because it'll be the basis of everything else. Now, group the feathers - the number of groups depends on how many places the wing will be bent in. In out example, the bunny's right wing (our left) has 7 groups - 3 of them are the 'hand' part - long feathers, middle feathers, and smaller feathers, and another 4 are the rest - long feathers, middle feathers, group1 of small feathers, group2 of small feathers. The reason for this is being able to tinker with the lighting in a more effective manner, and prevents clutter of objects if you're bringing the file into Painter. Now, if there's something about those gradients you want to modify in groups, it's the right time to do so. Done?
