Too close for comfort?

SHOULD I BE CONCERNED? the water heater exhaust flue is above and to right of furnace flue. I don’t think its quite right, but maybe i’m being too picky??

I think it can possibly cause issues - i’m not an expert in fluid mechanics, but seems as if there is enough potential for an issue…

what do you think, what is your experience, advice on this?

The water heater flue turning down is an issue as far as I’'m concerned. Write it up.
