Soo, myself and another one of the Devs are a little bit lost for words on how to describe it.
In basic:
It's absolutely Beautiful (there were a few obscenities in between "absolutely" and "Beautiful")
Well done! Hopefully the rest of the team will like it too!

Actually constructive things for anyone wondering why:

1. Really love minimalism, wow you hit it.
2. Colours you chose are Great, love the mixes with Black and Blue (love that blue)
3. You went above and beyond on this submission, Scene's and Profile pictures!
4. Honestly It's great!

Another thing, just kinda thought of this =D
The language that we're generally using is Java, in this language { } and [ ] are used A lot more than < > ({ } the most). If you have any ideas on incorporating that too, that'd be awesome =D
Although, i'm not sure how that'd like comparatively (Not a graphic designer myself)
