You did your inspiration justice. Your drawing seems like it got pulled right out of the story! Besides his obvious facial expression, I appreciate the detail of the folds created by Kagome clutching at his collar. You can definitely get a sense of what each of them are feeling/thinking in this moment you have captured. Great job!

That look on his face is priceless! Love it! And I do think it is perfect like that, don't really need to colour it.
