resthouse 1st render in podium

sir / maam...this is my first post po using podium.... pakapa kapa pa lang po.... I don't know how to create bumps sa materials here in podium and as well as I don't know how to use hdri as sky here in podium. This is my first try. C&c are welcome.

workflow : su8 + podiumv2 + photoshopcs3
house model is not mine

enhancement nalang siguro sa photoshop.
adjust curves sa photoshop.
darker water nagmumukang tubig ng pool. sa photoshop narin.
yung palm nakikita yung edges niya. sa podium ba galing or edit sa photoshop yung palm?
background medyo saturated. try nmong palabasin yung colors niya.

nice presentation kunting re touch sa ps

nice sir
