I have a respect for people who translate their costumes into the real world, and for that I applaud you. This is very nice
In terms of a critique, I'm curious as to what you would like to hear? If you're going for your 'own take' on Link, then that is pretty hard to do especially if this is your idealized costume...
But in a general sense, I like what you did. The shield looks solid and practical for carrying many of Link's go-to items. (I've never seen that setup for the boomerang before) As well... you problem solved the sheath for the master sword pretty nicely. (Although, be careful with that sword! It is meant to be a wall hanger only! I'm sure you've already noticed how blade-heavy it is)
With the costume, if you're going for the real world feel I would highly recommend doing some kind of light tea-dye on your undergarments... The whites are pretty pristine and it is somewhat distracting/ detracting from the overall feel of your costume.
With the wig, I like the dirty color... but it should probably be longer! Many links I've seen suffer from the "school boy" syndrome from having short bangs on their link wigs. Whenever I have styled my wigs I use something longer... perhaps shoulder length but with the right color and body, and then trim it from there. If you don't want to attempt cutting it, you can always take it to a hairstylist. They are used to cutting wigs
But like I said this is a nice real-world translation! You look like you're comfortable and could give/ take a beating without worrying about something falling apart haha.
That said:
If you're going for a specific critique on accuracy between Twilight Princess, or OoT. There's quite a bit I could add but I'd leave that up to you
