Scanning color negatives is a challenge, no doubt. I scan hundreds of rolls of film every year and sometimes it just won't come out right at scan time. In Photoshop it's relatively easy to correct, often by clicking "Auto-color" or by setting the white point using curves. When printing it's also easy, just dial in more of the color you want to take out. I think you should take or mail this negative to a proper lab and have them print it. If it's still too blue they can correct it.
On a side note, that's an excellent photograph. I share in your joy - sometimes nailing the focus is a prize in and of itself!
