Those concepts for the kraken look awesome! And having a kraken for the naval units for the elves is just well, awesome! It's incredibly unique and cool and just wow! I didn't expect something like this at all! This is an extremely pleasant surprise, and I can't wait to see how it plays out in-game!
I love the little boat off to the side and in the last screenshot it has the "very bad day" thing pointing to it! It also really helps see how HUGE it really is.
