@EliansProductions thanks for your answer. The Sky trailer is a complete different kind of music piece (other genre), but I can always add more developement. Just thought it wouldn’t fit this kind of production and the use as background music. If I develope more, maybe thats another rejection reason… Beats me what another reason of rejection could be. Thanks for the help.
