What's up with epic's picks?

My 2nd map I made got accepted into epics picks and I thought that would be a good sign, but now I’ve had 4 maps that are much better than the one that got accepted get rejected. The last map I submitted has an avg playtime of 26 minutes!! I also made a custom time of day/weather setup that allowed for almost photoreal graphics. Here’s the trailer

Can anyone give me any tips on what I need to get featured again? Epics picks is the only way I’ve made any money through UEFN and soon I won’t be able to afford to work on maps anymore. Code for the mentioned map is 1850-7602-6602
