The elephant is reflected in the mirror...The frog needs a reflection as well for consistency.

hi..thanks for the great suggestion,I'm grateful with you,i hope i can learn more.

dats a big frong hahah

I like the colors! There's something very charming about the big frog and li'l elephant.

However, the "two" elephants don't work convincingly. Without a reflection of the frog (which would have been hard to achieve because of the angle of the shot that would have been needed), one elephant would have been better.

Also, for next time, watch the "leftover" background in spaces when masking. Specifically, there is original image "background" left uncut inside the curl of the elephants' trunks.
