I've recently gotten into a custom dndD&D-like role-playing campaign and have developed my character to be a quiet, contemplative, rogue andwho has a backstory that mostly represents a lone wolf.
I've just finished up with my second session and I think the DM is getting the idea that I'm just a quiet person or that I'm zoning out during play. As we're playing over roll20.net and skype, it's a little harder to convey body language than I would prefer. I also find it difficult because the group seems to really enjoy talking in first person when they speak and/or describe their actions. I've considered the possibility of using more emotes (ie. "Character shifts his eyes towards the door", where Character is my character's actual name), but I'm not sure of the effectiveness.
The end result is that I think my character is the type of person who would prefer to stand in the shadows for a combat advantage over involving themselves in conversation but I think that directly conflicts with my personal goal of engaging the group.
How can I play my character so that he is both believable and adds value to the group?
