ARGHHHH... the COMPRESSION.
Stupid 150kb rule.

In this case you are right... and I saw it when I posted it
The image has so much information in it, it required I go down to 25% (thats a LOT) in Adobe Photoshop to get it under 150
So here is the same shot reduced in scale so I did not have to compress it so much but still had to drop it to 50% none the less.
The amount of digital information in an image drives the amount of compression required. In that shot, it was sky high
