Greetings @RHyeok !
Amazing work! The sound effects in Reborn are great! It adds to the intensity of the scene. The shaky cam effect gave the feeling that there are two people present - one recording and one praying before the altar.
I’ve watched and re-watched Reborn 3 times to discover that there is actually a body on the altar that dissipates before the tentacled dark force starts morphing into a body of light. 
I really like how the energy changes from dark to light, and as a bright light, the character is dually full of dark energy.
I see this is a student submission. What are your aspirations upon graduation?
