This is really good… I love the detail you’ve put in, and the expression on her face… haa, priceless! The whole scene looks great, well done.
I have one small critique, the kangaroos left leg… To me it looks like it could come out a little more from under the body, so it moves more towards the right of the screen. Two reasons for this; one, the space on the bottom right of the image seems to want something in it to my eyes, in order to better balance the image. Two; his leg being so far under his body like it is, he looks like he might fall over or twist his ankle. You could bend it a little at the knee and move it up and to the right, make it look like he is moving for his next footing, might even add some more motion to his movements.
