@menalkhan Your art in my unprofessional opinion is ready to go. Your color choices and character designs are excellent.
I will say, however, based on what Jake, Will, and Lee have said in the past, is to be sure your illustrations have a clear story. I think the boy dreaming of his vacation and the monkey photos are there, but some of the others could be improved. For example, while most would recognize that as the story of Matilda, why is she in trouble in this specific illustration? With the duck and the bear, who are they and where did the slime come from? Why is the princess sad (Rapunzel?)? Don't just rely on people to know the stories to understand the art. And I love the tuk tuk with the chickens, but how much more fun that might be if they were driving it!
I don't believe you need to redo all the illustrations in your portfolio, but perhaps 2 or 3 key ones might make your story-telling abilities even more clear to potential clients/agents. And either put those at the top, or mix them in more rather than having them all at the bottom of the page.
And a few details on your site I noticed. The text is very choppy and rough. I would fix/change that to make everything more readable. Also, consider making your social links a bit larger if you can.
