Process Behind my Invite Giveway work

I uploaded this shot to show you my working process of the previous shot. How I sketched it before starting my work. How many things changed when my work just finished. And you may also able to see that how many things can be added.
Maybe This shot will help you to learn a few things, maybe your valuable comment will help me to correct my mistake also. Teaching and learning process is always my favourite though. Thanks to all of you.
