This has probably been posted before, but here is the character simulator that people have been using to make those animated gifs of subclasses (and every other class for that matter).
Program: どあ☆らて Ver.1.0
If the program auto-detects the location of on LaTale client and you want it to read from another (the Korean one =P), the simplest workaround is to temporarily rename the folder of the detected installation and move the folder for client you want to use in its place.
I can upload the Korean client if you guys would like, but I'll wait for some requests before doing so. xP
