The first thing once you've completed your character's look is to figure out a color scheme.

To the left is "Taramizu", a beagle-dauchsen mix. Both dogs tend to have earthy tones. I started picking out different shades of browns and tans to help complement each other. Everything else should stand out more (shirt, rose, butterflies).

To the right is the finished color key for the character. This allows you to have a visual aid and help plan out the character's colors.
