I really like this, quite unique despite its simplicity, mostly thanks to the animations.
A few suggestions:
- The death animation could use an explosion/blast. Maybe the building could shake a bit, and the plants could be scorched. Maybe the crate and the barrel could be on their side.
- In the decay animation, I would suggest having the base/ground not sink into the ground, it looks kinda weird ingame, but keep the plants, boxes and rubble sinking. Ynless you would apply my first suggestion, maybe have the plants turn brown too?
- It looks a bit weird to me that the water can is always visible. Maybe add a window sill for it to rest on, so it looks more natural?
- The underside of the foundation being closed isn't necessary. Remove those vertices/triangles would be more optimal.
And a few small technical issues: there's unused textures, a 0-length global animation, and some sequences don't have any extents.
Overall this is a nicely polished model with original animations, well done!
