any help would be nice
You could use computer analysis. This is available once a week for all free members. That will tell you doubtful moves, blunders etc., made by both white and black
At move #4 Bxb2 is questionable. You are exchanging a developed piece for an undeveloped piece. It is waste of tempo.
For beginners like me the saving a tempo is helpful to avoid cramped position.
