lukasz.kostka:
Thanks. For input. Now I will design a analog board. Will create a new topic for that.

I do not want to change VCC to be wider since it is impossible to route it between pins.
I've enlarged via pads.
Can't figure out a way for pin 4 VCC on atmega to go to a star point. IMO it is good enough since there will be little current.

That looks better but I would still aim for wider Vcc. If you move south edge further south that will make room for it.  Its better to have it neck dock through a tight spot and be wide elsewhere than it is to have it skinny the whole way.
lukasz.kostka:
It is fine. I have a 0.4 mm wide trace with 0.035 thick. It can carry 1.2 A which is way more than I need.
Kasper:
It probably is fine but heat is not the only reason to make wider traces.  If you want to learn PCB design beyond this one project, learning how to route power could be useful.

I was once tasked with finding and fixing false detection problem in 1000 motion sensors.  The PCB designer thought a skinny shared trace was fine.  He caused a huge problem for a small business that could barely afford it.  All because he thought it'd be fine to make the PCB 1mm smaller than it should have been.
