It's probably a good thing you didn't title it that as while some people genuinely feel that way when they title things like that a lot of them are telling themselves that but actually just sadfishing XD
In essence documentation is just noting something down so you succeeded there (it's possible but very difficult to fail at straight up documentation).
That deer is adorable XD
Your photos are fine, the biggest critique I'm going to give you about them is framing related, if you'd lined up the horizon and put it at one of the third points instead of around halfway (especially for your postcard shot where putting the horizon line on the bottom third would have had the entire tree plus some margin would have been it I think) you'd probably be complaining a bit less ;D Having been in this position many times (of just having to grab the shot as quickly as possible and not being a professional by any stretch of the imagination) I do understand lining them up can be entertaining.
Plenty of these amazing creatures around that place.
I got what you're suggesting with framing. I will try it in my next adventure. But my philosophy was to enjoy the place and be with it, capturing photos comes later. But I am changing that because I want to capture the moments with Little one forever. 💟☮️
Unless you actively want to work on your photography skills it's just something to keep in mind while you prioritise capturing the moment. Can't say anything for other people but I've found that I got slightly better just from keeping composition rules in mind while taking about a bazillion photos throughout the kids lives (I have a lot less now that they're adults or close enough :<).
