My thoughts about this god:
Hymn to Aphrodite - the 1.5% increment is completely useless when it comes to farming, why would anyone stack this spell when they can just rather use it on multiple cities? You would need to cast it 20 times to get 50% and only once to get 20%, was there even any thought put into this? Nobody will have 20 spells early game and mid game people gonna have more cities to cast it on.
Charitable festival - This is litteraly 130 favor for 6 bp that you save on a vp. I wouldnt bother casting this, thats how insignificant it is.
Sirens - Cool design but too OP as people mentioned, Im assuming that timing and cancelling attacks wasnt considered when coming up with this. Problem is that this discourages people who can actually time, its taking a skill away from the game. Devs wouldnt know this since they dont play the game, which is a shame.
Narcissism - maybe balanced, for big breaks people are gonna have athena's city protection anyway, always can just be purified (i hope)
Satyr - Probably as useless as any other myth that isnt a flyer, speed is not that good since to make use of it you have to send attacks made of satyrs only and landlocked
Pygmalion - Idk everyone has around 250 more pop now (225 + 10% of 225 with baths), pretty poggers for those big ls nukes people polish for 10 days and use them once a year, maybe we gonna see 430 ls nuke and said player who send it will call themselves best grepolis player. Jokes aside its very meh and we could have something with a better design, since you can cheese this by swapping out gods and going into negative population.
