Caricature order from Australia

The client resides in Australia.
She places a caricature order for this family, staying in Yishun, Singapore.
Requested me to mail it to them upon completion.
Sent her this softcopy upon completion, before posting it out, as a proof of work done.
You might have noticed - only fountain pen used again.
Any difference?

Feedback from the client:-
"Hey Jit,
That looks fantastic! Thanks for the great work!
Yeumee"
