Very interesting...
The whole concept of this flash is good and works, two strawberries befriending each other, getting into all sorts of shenanigans.
The animation needs improvement, since the movement is all static and still, you really need to work on that, for example; give the strawberries arms and even legs if you wish, it will make it looks so much better when animated. Practice on Flash for at least a month, and you'll come back with some great results.
It wouldn't be a bad idea to make a part 2 of this, especially if you improve the animation, as I said above.
Overall, this isn't bad since it's your first. I hope you look into and understand this review :D
