New Kitchen/Bathroom Drainage - Help Please!

I've recently renovated my bathroom and kitchen; however, the tub, and both sinks (kitchen and bathroom) are draining extremely slow.

I did not change any of the plumbing in the bathroom, however; I relocated the sink in the kitchen which included relocating some of the ventilation for the kitchen sink.

I am not sure if this is a ventilation issue or a clog issue. I've provided a link to some pictures of the plumbing configuration:

Any help is appreciated.

Thanks,

from the looks of the picture, I could be wrong, i see a ptrap for the tub, with no type of protection to keep trash out during construction.

trash in your pipes may be your problem.

I agree here slow drainage indicates a clog of some sort. If it is manifesting in tub and in kitchen sink both lines will need to be cleaned out with a snake, because both are blocked up
