Greetings dear sister @roohiasif99 . Wow your drawing is really beautiful.
I like how you make every step with care. The car and characters look so cute together. Dora, monkey and dog sitting in the car is such a nice idea. Your colouring is also very clean and bright, it makes the drawing alive. I can feel you enjoy your art and that joy shows in your work. Everyone must be very happy to see this. Keep making more drawings, you have real talent.
Best of luck for the contest.
