Critting the Signless is a bit of a tricky proposition, because this is a bit of a YMMV issue given that his characterisation hasn't been explicitly spelled out. Consider these more ideas to consider rather than hardcore 'you must do this' sort of crit.
I think you play the Signless a but too soft and gentle. Yes, he's more sympathetic and empathic than the average troll, but remember that he's had to survive in that society. He can't afford to show much weakness, because others wouldn't respect him for it, and that would be counter-productive to trying to convince them of his ideal of what he thinks the society should be. It might be helpful to go look at Kankri's behaviour in the canon, because while it was stated that Signless acted with more maturity (and less insufferability) that him, his personality should give you a bit more to work with on this angle. Kankri believed that he had the right idea about all the issues pervading Troll society, which lead to him lecturing and pushing his ideas onto other people, overriding them with the sheer QUANTITY of his arguments. Though Signless shouldn't be quite that bad, I'd still like to see more passion in him, because after all, he's lived in a society that would have constantly ridiculed his beliefs. He would have had to fight, to stand strong, even just to get people to hear him out.
And basically, I don't really see anything of Kankri in Signless, which probably shouldn't be the case, because they are, after all, the same person, and that's the only really solid characterisation you have to draw from.
