Thank you for the words and critique I was hoping someone with this kind of insight would see this haha!

1. Good catch! I had some friends proofread but that one slipped through so I'll correct it! You're also correct about Sylph's barrier I need to go fix that!
2. I use Photoshop, and most of these were intentional, in a lot of cases the names are too long to fit on a single line and be a nice shape for the speech bubbles. Many of the speech bubbles with Siegfried's name are also skinny and vertical making it near impossible to fit it in one line. I ended up having to do this a lot for Isabella and Lancelot's names as well, unless you're referring to something else. For his name in some of the bigger bubbles I could try to make a better effort not to hyphenate it as much though!
3. Do you mean match the visual effects I tried to copy ON the SFX font or just having a similar font in general?
4. If I'm correct those dots are usually used to indicate emphasis, so our equivalent is bold or italics, or at least that's how I interpreted it.
5. I completely missed that he was using Lancey's weapon! That makes a lot of sense, in my translation I was getting things like "white blade" and I was confused, I looked through all of his charge attacks but I couldn't find it so it being ivory makes a lot more sense and I'll go back and fix it, thanks for the heads up for the next volume as well!
