Here we have dreamydemon with an original version of Dark Link!
Overall, it looks like the costume itself is well-made and fits your body properly (as far as tunics go!) This is great, since that’s a huge thing you don’t have to worry about.
The first thing we noticed, though, was your shield. It appears as though you’ve created a version of the Mirror Shield. If that’s accurate, then perhaps painting it in such a way to make it actually shiny would add a LOT to the prop, since the mirror shield is meant to be reflective.
On the topic of the shield, the black border is sort of sticking out, since it looks to be made up of individual pieces, instead of looking like one solid piece like it’s meant to. If you don’t want to scrap it completely (which you shouldn’t have to, since overall the construction is very nice), I’d recommend filling in the cracks with something (like paperclay or plaster or something of the like), sanding it down smooth, and then painting over it so it has a more unified feel to it.
The only other thing we noticed were your boots. While those boots are the correct color, the style and material are not accurate to the time period the games reflect. We highly recommend replacing them with something more fitting of the character. If you’re unable to find a pair that look correct, you can always get a cheap pair of shoes from the thrift store and make your own covers for them.
Good luck with your renovation and future cosplays!
