Somewhere In my Memory - Piano/Violin quartet

Any deal-killer problems here?

I listened on my laptop speakers and then I listened again with ear buds on the same laptop. Sounded good to me both times.

sounds good.

Cool. I’m sending it.

The only thing that stuck out to me is that the general tone of the strings feels different than the piano. The piano is very up front while the strings are sitting farther back. They sort of have a “different rooms” effect going on. Is that a real piano or VSTi?
