Thank you everyone
I am really happy that the first Items made it to the store. 
Nevertheless I am a little bit disappointed in the Devs.. this is what I sent them (left) and how they implemented them (right)

It might be not a really big deal but still.. I gave it all to make them look as real as possible and I think that my version looks a little bit better.
I already sent them an email and asked them to fix the HeightMap with the one I send them and really hope that they will consider fixing it.
Fingers crossed that the other pieces (especially black velvet dress and corsets) won't suffer a downscale like the boots.
