Hey! The render itself is pretty awesome but I'd lose the black border for sure, change the font, use a more techish font. Id put it right under the smaller image or in the middle bottom right and make some unreadable tech underneath that, maybe some barcodes or something. I think a subtitle type thing in pixel font would look cool too. A lighsource wouldnt be a bad idea either.

I like this font right here, dont know how well it would look.
