The thickness seems to be the one thing I'd like to see improved in future versions. Overall I like it, but some of the renders preceding the launch imo look better. It seems that they focused more on fashion and style, than utility. Like, they could have stowed the battery(s) in parts of the band, perhaps even on the bottom side (palm side) of your wrist, reducing the thickness of the overall watch. It's a catch 22... go for style, which is what they did with all the different bands. I imagine future generations of the watch will be thinner.
