Again, print a tiger with support.

Does the belly look "normal" coming out of S3D?

Thanks

There's plenty of settings that you can adjust to improve the bottom surfaces. Dense support, separation distances, infill percentage, even layer height will make a big difference. So what you're seeing is probably not too far from an initial starting point, but some experimentation and testing can surely improve it.

This is encouraging!
I am most interested in separation distance. How can I change the separation distance?
I am using 0.2mm layer height. I tried 0.1mm several times, it cannot even bridge through 20% infill on my printer. So I think 0.2mm is what I have to use on my printer.
The separation on the support is 1 layer.
Another way I can think of is the opposite of making separation distance smaller, but extruding 150% on the layer above the one layer "gap".
