For the first few years Brycing, I NEVER did postwork, save for JPEG conversion and signature. Bryce was all I needed at the time. Then I became weary of the Bryce "look," but didn't want to change programs. So I started experimenting with Painter Classic, Ultimate FX (one of these days I'll get Photoshop). I would guess that I use postwork on 95% of the images I post. It just depends on whether or not the image can be improved with some adjustments. Also, postwork can be fun :-)
