I gotta say, I really really like this design. Combining the portals with the bar at the top would be really nice and make everything look more smooth, and I love how the placement of movies and games would make them stand out even more and make everything look less cluttered. I do think that showing icons with supporter icons would make it look more homey, but I'm not much of a graphic designer so it's probably best to take that out anyway.
I don't really have much to say since you elaborated a lot in the description (which is absolutely not a bad thing) or anything to give feedback for aside from non-objective stuff.
