1. He got blassgrüne Augen in the German version, which is probably not as noticeable a word as glaucous is, since it's a compound of two rather common words. I remember having a big struggle on how to translate that since it's sorta not that defined (outside of the RAL-color pattern, but I think perception of the word is different from the exact RAL-color).
2. Lol yeah sticking to what words your character might use rather than what you would use is more challenging than what people think, but it's a quality of a great writer to get that spot on...
3. Yeah, probably best to first write and then post, but that makes all the feedback only half worth it... Can't really change a finished story, or only with large difficulties... Did I mention Gemini was finished in November 2013 but I rewrote the last 20k words to like 50k+ and completely changed the ending? That was because I wrote it first and posted later and the first comments made me realize what things I had completely overseen...
I would love to write again (or feel like it from time to time) but I know chances of me getting anything done in the next few years are slim so better not start...
