What are the good qualities of your playing/DMing and bad ones? (Its up to you, which qualities you consider good/bad)
I think that one of good qualities of my DMing is that, when I have to play an NPC bard (for example) I play him very naturally. It means if in the storyline the bard sings something, I take my guitar and really play and sing (and not very bad it seems). The players are fascinated. Some ask for more.
My bad quality is that I may seem too strict about the rules. Some find it limiting players imagination.
