10 to 15 seconds in the developer is really short, and it looks like over exposure as well. Adjust your exposure so you are more around 30 -60 seconds in your developer to allow for more even development.
Light leaks in the "camera" as well could cause fogging.
Could you have mixed the developer wrong? Maybe, what is it, dilution and how are you mixing it?
