Awesome stuff! I think all three tracks are in need of additional mixing and some mastering to brighten them up and bring out some power in the synths, but I'm assuming you'd get to that when/if one of these gets close to being finished.
The first song caught my attention the most. Sounds somewhat inspired by Rogue or Au5 maybe? The kick and snare could use more layering and equalization to help them punch through more effectively. It's essentially a simple beat over some sidechained synths and bass - Not much to it, so I think it's important for the drums to really blow you away on a song that relies on so little. Nothing wrong with the simplicity, in my opinion.
I think you're onto something with these teasers. I wouldn't describe them as uncreative or horrible by any means. In fact, it's better than most of the stuff you find in the audio portal and it's pretty obvious just by listening to these WIP's that you have experience. Keep working and release these! :)
