Hi @audiohamster! Sorry to hear about the rejections - I think it’s a common part of every AudioJungle author’s story so don’t take it too much to heart!
Here’s a few things I noticed listening through:
Samples feel a bit outdated, particularly the bass guitar in “Inspiring Corporate Motivation”. I would stick to a synth bass or playing the part with a real bass rather than emulating a bass guitar (which is really hard to do with software in my opinion). The vocal parts in “Uplifting Upbeat Acoustic” also feel quite artificial. I think the market really values “real” sounding instruments!
Some of your melodies are quite complex and move a lot. Place yourself in the shoes of an editor that needs to use this music underneath someone talking. A complexing moving melody makes this a lot harder. Simple, short phrased and repeated melodies seem to work best for the corporate genre. If you’re layering melodies, consider panning as well to leave some space in the centre for V/O.
Work on your endings. The first track ends abruptly, as does the second. People are most likely using your track to tell some type of visual story, so if you don’t give them an ending you’re not giving your track the utility it needs to be helpful to their needs.
I think song 3 (Bright Upbeat Motivation) is your best track for sure. All three of your tracks have a good mix and volume, though, so I think with some improvements you’ll be well on the way.
Don’t be discouraged though, there are so many tracks that to my ears sound amazing (better than anything I could ever produce anyway!) that get rejected. Keep persevering and good luck!
