The question is do you like it? you are the one who you need to please. What I may think of it or what someone else may think of it could be widely different view points based on a number of things our tastes in color choice or design choice weighing heavily on our opinions.
I can see care in prep work was an important aspect of your creation yielding a quality finished product so that would be my only avenue for comment.
I happen to like vastly contrasting colors as in your door being black in an all white room there are other colors which would achieve the same visual effect as well.
So I will close by saying good job from the standpoint of quality.
