I know that you're trying to express enthusiasm, but this statement comes across as insulting. It suggests that the task is trivial, and hence if someone

It's much safer to talk about how much you like the design, or how well it fits the SDT game, or how you'll be grateful to the person who completes your request. Speaking of which: it would be polite to visit

It's also helpful to notify an artist that their work has been reposted elsewhere (such as Rule34). Usually they'll be happy to see that their stuff is getting greater exposure, in a few cases they might ask for your help in getting proper attribution (i.e. linking back to the artist's webpage) or in taking down the material (if it's being used improperly, or if someone else is falsely taking credit for their work).
