This was quite interesting. Maybe you can make true dragons as previous owners of Elements, Even before 7 dragons that heavenly principles defeated. Veldanava as 'First Descender' and Lumine(Rimuru) as 'second descender'.
Pretty good work. The sub-titles were a bit hard to read. You may want to use a darker color for them. Other then that just practice and effort will allow you to improve over time. Also you might want to double check the spelling on your tag lines. It makes it easier when people do a search for a specific character. Best of luck to you.
