The characters are:

Markum Armor doesn't have to be exactly as pictured. You are welcome to simplify if you want to. The hood that can be seen in one of the refs should be down, hanging on his back. Weapons can be held or sheathed on his back. He's a rogue that loves to joke around and has a gift for finding the funny side of whatever happens (sometimes to the annoyance of his friends). His pose should be something that makes him look a bit cocky and his expression should definitely be smug. I'll leave the actual pose up to you.

Karric He's a dwarf rogue with a similar disposition to Markum but with a tendency to get offended when someone has other opinions than him or just simply rubs him the wrong way. In other words a joker with a rather short temper. The armor doesn't have to look exactly like the ref, as long as the feel of it is similar I'll be happy (and as it says, the helmet should be excluded). And it's the same with the dagger refs. His weapons should simply be similar in design. As for pose I'm thinking some kind of attack-related pose. Either with him getting ready to attack or he could be waiting on the enemy to make their move. Either way he should have a lopsided grin and look pretty confident. And his body build should be similar to the male dwarf in this ref.
