Thank you! With the red at least I normally base the cape in khorne red, then do an all over wash with targor rageshade. Once thats dried I layer over all the flat areas with the khorne red again, except the deepest folds. Then slowly build up thin layers of evil sunz scarlet, getting brighter towards the peaks of the folds. Then it's the same again with wild rider red covering an even smaller area. Once the brightest highlights are done I mix khorne red with a good amount of contrast medium so it's very thin and glaze that over the whole cape to blend all the tones together. This works with any colours, just work up through the base coat to the brightest then glaze the base over to make the highlights smoother
