I can't read or speak the language, but:

for : with small motions + exit, would "trickle" be better than "spurt out" as a verb?

I'd also say: flow of image over grammatical structure because the sense of structural language is so very different.

It's like swearing. In English, we swear. The Japanese decline verbs. The *effect* of either is similar, but a strict translation can't produce it.

(Also, the native Japanese speaker who lived with me for a year (to learn English) had some difficulty with our use of genetives).
