The summaries are too sparse for me to form a solid opinion on the characters, but the basic concept seems plausible for both of them. Ascian servant isn't too terribly implausible, but the Ascians generally only meddle in major affairs, so if he were a servant of an Ascian he'd need to be involved in something significant for it to be believable.
From what I can tell, you have qualms about the pirate concept because the druid concept feels more "alive". In other words, you view your druid concept as more of a person--as someone you might encounter naturally-and you view your pirate concept as more of a character--someone who is artificial or feels deliberately written .
Based off the summaries, you have Lukong's personality more sorted out with deeper detail, whereas the summary for the pirate gave me no idea as to what kind of person Katsumi was other than "ambitious". I think part of this is it seems like you wrote Lukong in terms of thinking what he is like as a person, but you wrote Katsumi as a concept--as an evil character or villain.
The key to writing a compelling antagonistic character--or really, any compelling character--in RP is to let them become an antagonist on their own. What I mean by that is you should write their personality, history, and so on completely independent of any sense of morality. Essentially, stop thinking in terms of "good guy" and "bad guy", and start thinking "person". Don't write that Katsumi wants to be a pirate captain with "because he's a bad guy" in mind. Write that Katsumi wants to be a fleet admiral of pirates because that is what the character would want for reasons x, y, and z.
Add more detail. Write justifications. Constantly ask yourself "why". Why does the character act this way? Why do they like certain things? Why do they dislike certain things? Why does he want this?
Write them as people, not characters.
