Zunächst einmal eine Klarstellung: Eine Domäne (domain) ist ein Teil einer Internetadresse, der weder ins Englische übertragen, noch sonstwie verändert werden kann.

Are these works that you do using other people's photos? If so, I'd make it more personal and attractive, like this:

watercolor-of-your-photo
sketch-of-your-photo
oilpainting-of-your photo

1) "of" für "nach" ist nicht richtig, es muss (im Gegensatz zu #2, obwohl #2 ist an und für sich nicht falsch) "from" heißen. 2) "pencildrawing" und "oilpainting" sollten nicht zusammengeschrieben und 3) die Bindestriche sollten weggelassen werden. (Es sei denn natürlich, (2) und (3) sind aus "technischen" Gründen notwendig, mit Domainkennzeichnungen kenne ich mich nicht aus.)

"watercolor from photo"
"drawing from photo"
"oil painting from photo"

@Manu
Danke für den Hinweis - ich habe geschrieben, ich möchte die selben Seiten auf Englisch machen, nichts anderes. Deine Belehrung ist natürlich völliger Unsinn!

Den anderen vielen Dank!

@Phillipp & Mini Cooper: The both of you are British. How come one contradicts the other? M.C., probably you didn't understand the meaning of the German? Or is your suggstion ("of") actually right and Phillipp's ("from") isn't?

Both of us are British, but have different backgrounds and ranges of experience. Actually my "from" is the standard translation of "nach" in this sense (the sense, that is, of producing a painting, a drawing or a watercolour on the basis of a photograph). Believe me, my entire professional life consists in translating art-related texts. MC's version says something different: "a drawing/painting/watercolour of your photo" (on analogy, presumably, with e.g. "this is a photo of my uncle"). As I said, it's not wrong. But, strictly speaking, "from" here is the technically correct option.

Phillipp, I didn't doubt your nor anyone's expertise. I was just wondering which of the two prepositions is the actually commonly used in this sense.

So now you know ;-)

Alf: Phillipp explains it perfectly. Our translations have slightly different meanings. As I pointed out, my suggestion is for paintings or drawings copied from people's photos, and it is very much advertising language. Phillipp's translation on the other hand is more artistic.

Perhaps that will make it clearer to you.
