Personally I use whatever tools I have available to make my art look like I want it to look. Occasionally I have a model that doesn't conform the way I want, or a joint that is overly compressed, or maybe just a simple poke-through. These are things that should be corrected in order to make my art look more professional. Often I look at art in the galleries with the proclamation that no postwork was done, but as far as I'm concerned that is sort of like saying that one is not interested in finishing up the piece. Most of those no-postwork pics could really use it, IMO. Best Blessings, --Invidia
