Aw, so cute~. It did take me way too long to notice Holy Rome and Chibitalia in the sky though.
I do believe that HRE is Germany, too. Or a reincarnation or something. In history class the other day, we were talking about the Holy Roman Empire and my teacher was like, 'And, if you didn't know, Holy Roman Empire is Germany, alright?'. And I thought, SEE?! EVEN THE HISTORY TEACHER AGREES!
I do too... heck, i thought HRE WAS germany first time i watched hetalia. Before you ask if i'm stupid or anything, i was distracted by my best friend's little bro who had a crush on me at the time. He was being weird and like "H, E, DOUBLE HOCKEY STICKS" i was gunna let tha little weirdo out of my sight...
AHEM! Anyway, great picture. It gives me the warm happy fuzzies.
Have you read the Hetalia strip "Buon San Valentino"? At the very end of that strip, it hints that Germany is HRE cause after he had a mental breakdown, he recalled a memory in which he's giving Chibitalia a bouquet of flowers (and it's in Germany's POV). That strip also screams Ho Yay for GermanyxItaly fans.
On topic: I love this! You did a really awesome job with the stars and how Germany and Italy are illuminated in the dark night! I'm fangirling over this right now
