Set ups like that look nice, but aren't the best for a few reasons. Firstly the gravel will trap dirt and quickly make the water area unhygienic and the heaped up substrate land area will do the same. In addition to that the water area is much too small to be able to keep water quality and temperature stable for any length of time.
If the newt you're getting is genuinely a captive bred juvenile, the best set up would be a bare container with a damp paper towel substrate, a small, easily accessible water dish and some small hides for shelter. Although a tank like that doesn't look so good, I've found it to be the best way of keeping very young juveniles. As they get older and bigger, they can be transferred into a shallow aquarium that's crammed with live plants to prevent drowning until they eventually start to swim and submerge. After that you can slowly raise the water level until the aquarium is almost full with just a small island or cork float for a land area.
Tanks that have a 50/50 land/water area aren't really suitable for most newts as they are either fully aquatic or seasonally aquatic, so 50% of a land/water set up is always wasted.
