Id say my strong suits are interesting and varried terrain, nature and simple habitats as ive gotten quite good at making something plain look beautifull, which all comes together into some great panorama shots i might put a bit to much effort into
My building of exterior shells for building has also improved alot, with some simple adjustments to how i tackle them really helping me to make them look more interesting consistently.I also finally got a grasp on the path system to build some rather advanced paths, with the most impressive thing being the interior of my tropical house, that s was a pain but im proud
My biggest flaw is that i often build something and then do not touch it for eternitys. Something can be 95% done and i will take over half a year to finish it, if i finish it at all, which is why most of my zoo looks far worse then it could as those final finishing touches are missing.
The biggest culprit among that is doing actual interiors of buildings and doors, i just postpone them forever.
I also feel that while my general layout feels good, that the stuff outside and inbetween the habitats is often a bit lacking, either being very basic or just none existant, but im trying to get much better at that to add some more interest and spark to my zoos.
And lastly my creativity is quite hit or miss, with sometimes very ambitious idears and some nice creativity but at the same time i often default back to the same decoration sheme and a themeless enclosure, resulting in habitats not exactly looking the same but at the times just not being very eye catching
