Melon Intros

Hey I'm 14 years old (state 2018) and at the moment my hobby is making intros, for a relatively low price or free.
Why do I sell my Intros:
1. I need to buy lightrooms and other c4d stuff.
2. Intro making is not like typing in a text and the computer does all the other things. No, I need to do all by myself and want something in return for that.
