It looks good. However, I think it could look even better. I was hoping for you to use light helvetica. Also, I think the logo would look better without the blueish background, pretty much like it is in the very first image and what about a more stylish logo?
A theme with a predominant presence of white would be very nice, combined with red and black. I am sure it'd look really elegant, although you might overlook it because of the existence of the main and grayscale themes. I hope it's coming this year, since we've waited for years but I understand it's a long process, congratulations.
I cannot wait 
Mess at you being able to tag people now. 
That's going to be a MESS.
