Hi Provoquemedia, this is just my humble opinion but I feel that your mixes and arrangement are lacking in dimension. The arrangements for all of the tracks don’t have much variation so are quite repetitive and the percussion stays the same throughout most of them. I think a good bit of panning and reverb would help but you also need to make your arrangements more interesting. I’m thinking about break downs and build ups and layering instruments to change the timbre, which will make it much more interesting for the listener and also more usable for video editors. The strings for your epic cinema track are quite fake sounding so investing in some good sample libraries would help!
Hope that helps and good luck with your future submissions! (I’ve had loads of rejected tracks so I know how it feels )
