That looks pretty good. If I took pictures of my biggest project, it would look 4.8 times worse but they don't want to pay to put everything in a rack, make it pretty, so it's wires going everywhere. Having spent years in data centers, it's not like I don't know how to make it neat, but neat cost time & money.
The best installers I've used did 3 things that are so awesomely insane it's worth mentioning. Smart Systems Technology in Irvine, CA, we hired them to install access control about 5 years ago. They used a new technique called an air battery where they put the battery inside the enclosure but did not connect it to anything. Somehow this did not work out as well as they thought during the first power outage. The good news is they agreed to come back and wire it for an additional $304.60. The contract said battery backup, but apparently attaching it was extra. The second act of genius was to put two power supply boards in an enclosure held in place only by the wires that attached them. Over a few months time, they sagged and touched each other, also did not turn out well, again offering to fix them under warranty for a price. Lastly, they installed an electric strike meant for a panic bar, but gate had a cylindrical lock. With careful monthly adjustment, we were able to make it work, until 5 years later when we installed a panic bar which wasn't easy because the gate opened the wrong way, yet another act of pure genius.
