Maybe this is the most important part yes !
About violins it’s pretty hard to say, I’m not expert at all so I won’t have an accurate point of view ! I guess it’s just my taste ?
The last advice that I could give you about rejection, (Because I’m probably the most rejected author here ) is to move to something else,
Don’t waste to much time if you think there is too much issue to correct or whatever. Each finished track is a step forward, and step by step everything will improve and then approval will come !
DOn’t forget that AJ reviewer become really strict full, but don’t try to only please them, it’s a trap
AND obviously there is ton of other library, AJ is not the center of the stock music world,
The market is over saturated and slow, so AJ is no more the leader, slow sales , slow views, and finally looks like other stock music website !
Time are hard so you have to find a place where your work could be accepted, Never give up about AJ even it’s hard and bad for self-confidence etc si for this track, just move on
GOOD LUCK , just keep to work
