You're welcome. I was happy to help.
Whether or not you select and fill or use a paint brush to manually color an image, it's all the same. If the selection is fairly easy I will go that route if it's easier to paint with a brush I do that. There's more than one way to do just about every thing.
However, one of the best techniques that will save you headaches in the future is to keep your colors seperated on different layers so you can adjust hue/sat or use layer masks to control a color bleed into another color and even adjust the opacity individually since some colors can be more intense than others. Also, don't be afraid to experiment with various blend modes (besides color) and various opacities. You may find some cool techniques of your own in the process.
