The lines at the bottom is a bit unbalanced vs the arm bands. Could have used a bit of a wave there too maybe, or maybe it was a bit too much.
The shoulder logos are a bit uninspired, could have maybe used a "K" in there or in the logo maybe. Or maybe even spell out the name somewhere.
The Main logo itself looks good, I love the tentacle incorporated in, love the ferocity that it conveys.
EDIT:
Ok I will recant my judgement on the shoulder logos, it's much nicer when I saw the detailed work incorporating the Space Needle. https://www.icethetics.com/news/release-the-kraken-seattles-nhl-team-finally-has-name
But the Wordmark is troublesome because I'm not sure if the first K is a capital or not in that font. Seeing as it's different from the 2nd K, it must be but there are not enough distinction between the two.
