How can I do good code reviews, to improve even more I want to review myself. To find bugs or even better things how to implement them. How should I proceed [1.,2.,3. etc.]

Reviewing code is just about checking the code satisfies the brief and is free of bugs really.
If you have a test suite then some sort of CI process should be able to run the test suite when a pull request is opened.
That will catch any logic errors (so long as you actually have test coverage for the feature being developed).
And as reviewing PRs requires care and attention, it then makes sense to keep PRs small in terms of changed files/lines of code changed.
