A while ago, I created a set of adventuring fantasy characters, and have already written almost 3 short stories in which they are the main characters. However, as my stories progress I find myself encountering a few difficulties. First of all, my characters are friends, and they travel together, but I can't seem to keep track of what all of them are doing at once. For example, when the five of them are having a conversation I tend to completely leave out 2 or 3 characters and focus mainly on 2 or 3 specific characters, even though the others are still present in the conversation. This irritates me, because I want them all to be involved, but I don't know how that would work out with five characters. Secondly, it's hard for me to give each character its own special personality. In the beginning, I had a plan set out for them; one would be the leader, prideful and somewhat boastful, one would be optimistic and cheery, and one would be quiet and shy. But now they all seem to blend together. Does anyone have any advice on how I can fix these issues?
