Shouldn't there be an inventory section or something similar in the CS? Obviously characters that live in Estermere will have a lot of possessions that won't necessarily be a part of their present inventory, but I find it's very helpful for keeping track of what each character would be expected to have on them at any given moment (and it also deters people from "finding" health potions in their pockets later on down the road, although this is rarely a problem with the right group of players anyway). I think this would be especially appropriate considering this RP takes cues from DnD, which as we all know is fairly specific when it comes to inventory management.

Also, for characters with magical powers, shouldn't there be like a magic/abilities/skills section that allows them to explain those powers in detail? In my experience it's a lot better to make sure the strengths and limitations of magic and abilities are outlined clearly before the roleplay starts to avoid problems arising later. Given that this is a character driven roleplay I'd say having a balanced cast of characters would be a pretty high priority.

Sorry to be full of suggestions, but I noticed that it's your first time GMing so I thought I'd offer some of my advice. There's no real downside to having more information about a character aside from the sheet taking slightly longer to fill out (and if they're too lazy to fill out two extra sections of the sheet then I'm not really sure you want them to be a part of your roleplay to begin with). I'd be happy to assist you as a co-GM too if you'd like.
