Looks fine to me from here

Only 2 comments, i would move the fan up to line up with the exit, the ducting has 2 unnecessary 90° bends and 3m of duct it does not need. Each bend saps something like 25% of fan power and the metres also take a %

Then, exhaust your air outside, the hot, humid, lowered CO2 air is away and gone, if you just recirculate the house air you will probably get problems and lower yields.

I can't really see or imagine how your setup works, so can't answer specifically, but the trick with exhaust, ducting is to keep it as short as possible, with the least amount of bends. Where you must have bends, I would always do a more gentle curve, rather than a sharp 90deg bend, purely based on layman's seat of the pants view of airflow dynamics.

You could also get a galvanised steel 90 degree bend from a ducting place (or a rubbish skip/scrapyard) as these have nicely smoothed internal bends, the concertina duct that is light and convenient and sold in growshops is not the best thing to make efficient corners with.

If noise is an issue, the acoustic double skinned ducting is magic

is that a 4 inch filter? i would upgrade when possible. i had one, lasted like 2 weeks in beginning of flower before i realized it was useless. i keep the filter and fan inside and strapped to ceiling and just vent up out of the top. nice setup, i doubt a 600w will produce enough humidity into that room for it to be an issue unless you have like no airflow in there.
