Yep, that’s exactly right. Xしか～ない = nothing but X.
As with pretty much any manga, the art actually gets better as Amano-sensei gets into the feel of things. Reading over this now, I’ve noticed there’s a few things which become familiar in later chapters have yet to make an appearence so far. She never gets any better at drawing cats, though. 
Amano-sensei actually visited Venice in person to get reference images for Aria.
I literally would never have made this connection or understood this sentence myself - thank you so much 
Are you insulting アリア社長 ?!
Thanks for the confirmation on しかない

Just wanted to chip in with my own translations for the top 2 boxes
Top right: Nevertheless, I often hear that the exam to become an undine is challenging
Top left: Probably because it’s the iconic job which symbolises the image of this town
Next box down
Akari: But I really want to row a gondola. I mean, there’s nothing else a woman can become apart from an undine, is there?
Postie: Well, that’s because all the other rowing occupations are male specialities.
Super late catching up here~
I’m a bit confused by a sentence on page 8
ずつとずつと憧れてたんです
Does this mean “little by little, I was attracted to it”?
I’m trying to figure out what’s happening to the verb here. is ～てた te-form with -た for the past or something? I’m assuming ～んです is explanatory tone?
The font is a little bit weird - it’s ずっとずっと I’ve aaaalways been attracted to it.
憧れてた = 憧れていた = 憧れている in past form
ohhh that makes SO much more sense, thank you!
How’s the catch-up going? 
just finished chapter one but a second ago–feels good 
on to chapter two!
Awesome!
