If I would have more than one up-vote to give you, I definitely would.
Although I have less professional experience than you, around 6 years combined in software development and information security, I've also come to appreciate people who find the right balance of taking what they do seriously without being uptight about it.
Which brings me to a trait that almost always puts a dent on my respect for anyone regardless of seniority: not asking enough questions and being quick to make statements.
I loathe this so much that I've turned the opposite into my work mantra: "no statements until there've been enough questions".
IMHO, this "small" tweak changes one's interactions and their outcomes with other co-workers for the better.
