You are entitied to your opinion, as I am to mine. As bonsai it does not look right. If the tree was a metre tall then the fruit would probably be in proportion. My concern is also for the health of the tree, if the fruit is left on it could kill the tree or at least weaken it greatly. I have seen Pomegramates with large fruit out of proportion, and they look odd. Fruit and flowers are often removed after a short time so that the tree can recover. I had cones on several of my Larch this year. I removed them so that it would not effect the tree.
I have to admit I have never seen an apple like yours in all the time I have been into bonsai, anywhere, in books magazines or nurseries or shows, so it could be quite unique. How long have you had it?
