I think the nose could benefit from using the BG color in the snot so it doesn't look like a mushroom so much as it does now. The N is good, but I think you should fix the hue shifting so it goes with the color ramp better. You go:
Light Yellow
Medium/light red
Medium Blue
Dark Red/maroon
Try something more like:
Light Yellow
Medium/light Red
Medium Magenta
Dark blue
