:3 Psst - try to add my tail :3

Oh btw - need any help with sai?

yeah,how do you make a custom brush?
and any tips on how to color would be nice,too =)

Well as far as custom brushes go - you can look for sets on net or click right mouse button on empty space in toolbox and add new one and configure it as you wish (it copies base of a tool) Oh and you can play with brush shapes - basically it's set for (basic circle)

Coloring? Well depends how you do it and what interests you the most :3 one thing you should look at is what tip you use for coloring - there are four of those and going some makes lines sharp but also it's kinda pixelized between two colors, other give smoother transition.

This looks awesome!
