HSB is a little foreign to me, but here it is.

Well this is why we introduce you to it...
There are some great uses for HSB. If you mask off a white area like the whites of the eyes or the teeth in a portrait, you can reduce the saturation and whiten those areas without too much hassle. It also has some advantages in flat images like the pumpkins.
The Idea here is to adjust the saturation to enhance the shape of the pumpkin. Try this...
1) place the mouse on the image in a transition area where the roundness of the pumpkin is defined by the color changes. If you adjust brightness you will drive the contrast through the roof and that is not the goal.
2) Note on the saturation curve where the color worm is. Try to limit your adjustment to that area of the Saturation curve at first. Try to be subtle. A little goes a long way.
3) once you have "shaped the pumpkins using the saturation and are satisfied that the colors have not "block" up. I.E. you still have details in the image and the color has not blown out the details. Lightly adjust the brightness to enhance the shapes a bit. again this should be a subtle adjustment.
Your end result: the pumpkins should look rounder and a bit more varied in color. the image should have a full contrast range and vibrant color.

I'm not great on subtle, but let me know if this is any better.

Subtle comes with practice....
You are much closer. In this example the darker more saturated tones define the shape. if you struggle with the saturation you might have to adjust the brightness a bit to bring some fullness to the tones. try small adjustments in the brightness by placing the mouse near the curve of the pumpkin and marking a point on the curve. > Mark > then set a point on the curve by clicking on the mark you made in the brightness channel. with the point highlighted use the arrow keys to move the point up and down slowly to see if you can find a better spot for it. real subtle like....
