Hi and congrats. The piece is a bit too dark. Unfortunatly you got the same brown haircolor as I, with a bit of green tint in your bio hair. It also resembles in your brows - the green tint. Problem is, that I haven´t found a way to get this green tint from dyeing products. So I would recommend dyeing you natural hair a tiny bit darker. For the most natural appearance you could also color your brows a bit darker to match the new piece - but I guess that´s a bit drastic
I would recommend getting a medium brown ash color leaving it in your natural hair only for no more than 3-4 minuttes. We are talking minor details, however minor gets major in direct sunlight. My five cents
