ok where to start.
focal in the middle is not good (study rule of thirds)
grungy effect looks tacky
weak flow
remove border
the focal is basically his right shoulder because it is on a powerpoint (rule of thirds)
no depth as the foreground and background are the same sharpness.
you should emphasize the light from his shoulders instead of behind him
not much going on, add more effects, maybe a c4d or some smudging
text is pretty bad, study text theory.
basically, read up on theory, read tutorials, watch shit on youtube, fit effects around the render/stock not the other way around.
also add more colour
