Your columella is likey deviated to your left due to a deviation of the edge of the septum in this area. If you want this improved a revision surgery can be done to straighten the area. Septal reconstruction or grafting may be needed. An in person examination would allow for a better assessment of what options you have.

Crooked collumella from below
First it would be useful to have your preoperative photos. Second it would be helpful to have some additional postoperative photos. Third you have an asymmetric nasal base with your left side higher than the right. The preoperative difference will make it impossible to achieve a perfect result.
If you have a crooked columella look from below, it is probably related to your caudal septum. This can be evaluated by exam.
