Drawing 'All Dogs Go To Heaven' for the Cosmic Creations

If I'm frank I couldn't place if this idea is a myth or not but it was definitely worth the shot. When I was a kid I used to hear this sayings in cartoons and oftentimes it is depicted in movies, and that is "All dogs go to heaven".
I've heard that saying so many times but never even knew it there was a movie about it till recently. I haven't seen the movie though but it sounds like good stuff.
In a way, the idea is relaxing because dogs are very loyal animals that go the extra mile to make sure you're well and that deserves some eternal reward.
With that being said, there was a lit of ideas floating around when I started the drawing. According to my inspiration the lower back of the dog was to tilt downwards but I wasn't able to realize this so a friend asked me to follow the reference and I did.
