Yes he is , especially for the younger ones.

Could it be just me, or does little "Timmy" in the back bear a striking resemblance to his father? Are they crafted from the same model, or is my imagination playing tricks?

Thank you very much. I'm glad you appreciate the effort. Yes, it actually took a while until everything was just the way I wanted it.

I can reassure you, your imagination isn't running away with you. However, the son in the background and Dad are actually from completely different models.
But even I noticed after rendering that they bear an uncanny resemblance to each other. OK, so I said to myself, why not, after all, they are father and son.
