Default Coolant Leak EJ257....Thermostat? Waterpump? Pictures attached

Hey guys,

Trying to determine where exactly a coolant leak is coming from in my 2006 STI. Took a few shots of the waterpump and thermostat housing.

Just did the headgaskets 30k miles ago. Along with the timing belt. Waterpump was done about 50k miles ago. Thinking it may be coming from the hoses off to the right side but wanted to get a discussion going to see what you guys think.

Thanks!

Update. Looked from underneath and it appears to be coming from behind the water pump.

Tough to say where the leak is originating from, but the hoses do look bloated. Were they all changed when the pump was changed?
