I have been trying for almost a year or two to make a game,recently last year me and my older sister found a game called Chzo Mythos which inspired me,that is how i found out about AGS. Unfortunately i wasn't able to find any tutorials on how to create sprites and backgrounds.So my questions are...

1.How do i make sprites that don't look ugly or dorky?

2.How do i make backgrounds that look good?

3.How do i make a midi file?

I am only 13 so i am not very good at the technical stuff,but i am willing to learn.

Thanks
