This is a very well done piece of animation. The way you make her stomach grow over short intervals gives the viewer a much better appreciation for the overall size at the end. The bulges are excellently done, and i like how whatever is inside of her actually pushes her boob up through squirming. The browing love handles and breasts fit in well too. My only small gripe is that her face is completle unanimated. If you could've added some reactions, or at the very least blinking, i think it could really improve the overall quality. Oh, and there's the little lines left on her belly each time it grows, detracts from the quality a little. But overall, still very well done.
It's a timeless flash animation theme and a very popular one. I thin khe sideways prose helps illustrate the immense size the model is going to obtain, and watching the process did make me wonder when it was going to stop! The movements that appear randomly from inside are unique to your style and a nice variant. The technique is a lesser degree because the "shadow" ofthe former belly size is visible and makes this seem unpolished. It's fun to see but a little more careful editing and testing will help clear up any residue of using the program to animate this. All in all, not a bad beginning to what most fans will be very happy to see more of.
This is the magic of drawing ^^ You don't have to doing realism if you don't whant. The only one point not negociable with me is anatomy. Peoples can ask belly very big I refuse to doing breaking body to support, I always adapt my work.
