I like it, the design is simple but appealing, gives a nice view of the components (especially the SSD, nice touch!) and seems to be relatively easy to build in. The way the cables are hidden underneath the PSU makes builds look very clean, too, so that's nice. Dedicated pump mount is a pretty good feature as well.
It seems like you could optimise it a little bit, though. 24L are quite large for an ITX case, even if it offers such extensive watercooling support.
First, you should consider moving to an SFX-L PSU. They offer more than enough performance for an ITX build, even with the beefiest GPU, and are very quiet as well. Though I do see the appeal this might have to someone who has built in a large ITX case like the Manta or Prodigy and wants to downsize. They don't have to buy additional components. Still, worth a consideration. Would also open space for more 2.5" drives.
Second, maybe you could shorten the case further by moving the 3.5" drive somewhere else or removing it entirely. At that point, there won't be space for a 360mm rad on the side anymore, but I don't think that is a particularly good setup anyway, as it looks like there's barely enough room for rad+fans, so they will get starved for air. I think you should focus on the 120+240 configuration, so make the case a little wider if needed, and shorten it if possible.
Though it seems a perfectly valid case as it is, and I'm not in the market for it anyway, so take my opinion with a grain of salt.
