So your power dissipation and consuming on 10,5 kohm resistor is around 8,8 watt ... to turn on few led .... no good!

And 220 rms AC are 311 peak !

In the end, is dangerous circuit due not galvanic separation from home electric net dostriburion.

4+Watt for the 10.5kOhm and 12Watt for the "3.48kOhm" the least efficient way to power LEDs from mains. Think about your alias "220V" and read something about peak- and rms voltage on Wiki.

Is better with 5.5 kOhm resistor, and is this capacitor correctly ?

7.5Watt, immernoch scheisse
