I made bodyparts, now what?

I’ve just started out, and I’ve made my first character - Sort off…He’s basically cut into pieces. Arms, legs, torso and head. Now, what do I do now once I got all the bodyparts? How do I link them together and how do I color them and being able to move the parts around without having the color leaving the colored area >_>
