Trying to work on bet sizing - any comments appreciated

Flush draw on the flop - bet for value and fold equity against a wide BU range. Fold weak broadways and medium pockets pairs. chose medium bet around 60%

Got a fold and then got berated for the play telling me I was a fish, now this is probably right but wanted to know if anyone would play this any differently. I thought this was a solid hand with a plan. Keen to know I misread this

Villan was decent player - loose side of reg
