It is tough to answer this question without looking at a photo of your nose, but even if there was a photo of your nose, I would tell you to find a plastic surgeon to examine you who does rhinoplasty and is comfortable doing revision rhinoplasty, or secondary rhinoplasty.
There are many techniques which you might need to improve your crooked appearance after your previous surgery. An open rhinoplasty approach is probably what most surgeons would do, and you may need cartilage taken from your septum, ear, or rib.
Your description of too much of the inside of your nose being seen leads me to believe that your tip may be too rotated (upturned), or perhaps the alae (the edges of the nostrils) are too high. These kinds of problems from a previous procedure can be challenging to fix. Again, seek out a plastic surgeon who is capable of performing this kind of revision surgery.
