First off, your followers may of have dropped because of ghost followers. Incase you don't know, ghost followers are referred to as people who don't look at your art or, if I'm correct, people who don't post of Colors3D for a LOOONG time. (Like 3 years... That's how long we're talkin')

Second off, I know, it's your gallery, you should draw whatever /you/ want, & draw for yourself, because the more you worry about getting more followers, the less inspiration you'll have. So, it's best to draw for yourself, have fun, & make some friends. ^w^
