Those lumps are from the medial crural footplate of your nose cartilages, which are normal to have. However, I do agree they are possibly sticking out too far from your nose and could be brought in closer together. That could be a relatively easy surgery to do (could even be done "closed"), assuming that nothing unusual was placed there on your first surgery. As for decreasing the amount of nostril show, however, it's hard to tell if it's a lot of show because you're tilting the camera upward or if that is natural. If it's tilting upward, then you also may need some articulating rim grafts to help lower the nostril show some. If it's really as much as this photo shows, then you will likely need composite ear grafts because you will need both cartilage and skin to bring the nostrils down. Good luck!
