OK.. interesting but if I may give you some advice, here some tips:
1- observe well the global main image... the giant biscuit is blured but not your tiny guy... you should use your blur filtrer to match the tiny layer with the giant one.
2- Watch…
I like this one; eye contact, looks real and the tiny one is 1/4th or 1/5th the size of the giant--interesting to see one where the small one isn't necessarily extremely tiny
