This looks very mottled and I suspect part of that could be the result of a light leak through the camera material or exposing through the wrong side of the paper as mentioned earlier. But, it appears to me that the development is also very uneven and I suspect that much of the mottling is coming from poor development technique. How long was your development? Also, it looks like there is a development line meandering through the image from not immersing it in developer quick enough. Be sure to give the image full development with constant agitation.
