I don’t think you can really make these comparisons, a happy uke track has nothing to do with your inspiring cinematic track and that future bass track has nothing to do with your motivational track, you need to look more apples to apples and find out where your composition/mix is lacking.
I will say from just listening to your two tracks that they are not bad at all, but they also aren’t really all that great. The two genres you’re competing in (corporate and cinematic) have some of the best composers on audio jungle in them already so unfortunately “good” just doesn’t seem to cut it most of the time and you need to be on a level with them.
In cinematic I’d say you’re a little too quiet/squashed so you lose a lot of the dramatics you need, also it is very repetitive, i’m sure it wouldn’t stand up to a lot of the competition that get’s uploaded there every day.
For motivational, it’s just too bland all around IMO. Composition and mixing just won’t stand out against what goes up there as well.
I’d pick some of the lesser done genres and focus on building your chops there, or really step up your game to compete in the genre’s you’re trying for!
And I had no idea you were a girl till you mentioned it! I’m sure that has nothing to do with it.
