There's something not right with the eyes... And solid coloring is not good for this picture. What you need, is to add a bit shining in the eyes and add texture to the background. Models and characters are very well made, but they're just solid colored as I said.
Yeah. Actually I don't make the (kh) a separate syllable... I just separated it in order to differentiate between "ck" and "k", which in this instance I'd pronounce a little differently from each other... though not as differently as I would like.
No one had thought of using the keys on a keyboard to create a completely original name. I use a qwerty keyboard. [link] The first 3 names were simply the keys typed in a straight row (Plus, they were the only ones that sounded like actual names.) The last one is all the letters that can be used in hacker language. [link] So yeah, there's only four, but they are, for lack of a better word, "ultimately" powerful.
P.S. Dvorak, (If you're referring to the keyboard) is an outdated keyboard that was made around 1936. Everyone uses qwerty keyboards nowadays. [link] Even Macintosh, except they have a few extra keys. [link]
