You may have seen a model of my mice before: (Delivery mouse). I try to do my best to make a cartoon with them. I prepared several frames from different scenes, and I will add them as it will ready.
In car: Add a very soft blue light behind the chairs, to me it feels like there needs to be more environment light, and it gets a little too dark. Their fur also feels wet or too thick to me.
The road: The windshield glass I think is too perfect I suggest adding imperfections to the car and the condensation can be tweaked to be more subtle on the glass.
I would also exaggerate the poses more of the two mice. The younger ones face more visible with his head tilted more out the window, and the older mouse looking like he is making more effort to get it started.
Also car license plate? And grill to have a more metallic defined look.
As I said in Delivery Mouse post, I can’t wait to see the final film. These stills are incredibly cute and I hope the story is as captivating as your 3D work! удачи!
“Christmas” is, of course, a classic subject, and I think that you have some truly spectacular ideas going on here. I look forward to the movie. I already know it’s going to be terrific. (Is it ready yet?)
