Much like explorers who sailed to distant countries for the cool stuff that only they had, my forays into Pixiv are usually aiming to bring back super soft draws and interesting compositions of incredible quality. (Either I'd already plumbed DeviantArt's most fantastic depths during my last journeys, or Pixiv is just easier to find gems in.)
Now, in all honesty I'm more of a pirate than a trader, but I'm still a man of culture and can appreciate good art. This is a nice example, because while this style isn't superior to others, it's rather consistent in its high quality and the site's got plenty to behold. :3
