image trace give different results on different size images
Hello!
I am working on a huge wall print ( glass ) on a swimming hall. I have made an exellent stippling image with photoshop rasterising plugin called Pixeology. Now I need this image to be traced in AI. I have made a great results on just a small part of the image - see here please:

This is traced. NIce, I got those same artistic small dots and feeling that Pixeology gives me on photoshop. But when I bring in the large, full image, like this:

.. and use the same live trace preset that I have saved, then the results are totally different. See here:

The small dots are not any more dots - some are triangles and they are not aligned any more in the beutifull way. I have tried to chage the live tracing settings to get the image look good but no results!
Please help me, what can I do?
