i am sorry Khadiza I will have to cancel your project as against my instruction you have been using copyrighted content.
I cross verified with Image search algorithms and found source of two of your illustrations as below:
Though these were not used directly but were copied by you. Irrespective of that I cannot accept your work.
I will make a refund request on the project and close it.
I am sorry. But if in future if you make good original creatives feel free to share them with me, but I cannot accept copied work.
