Who do you think my brother looks like?

Not sure.. Perhaps if you make him wear glasses he can easily resemble... Sweden, maybe?

He's looking down so it seems he has tsurime eyes.

Caucasian, tsurime:

- Estonia: geek
- Germany: too muscular; has different hairstyle
- Prussia: too perky; has different hairstyle
- Denmark: too perky; has different hairstyle
- America: too perky; has different hairstyle
- Canada: long haired and gentle-looking
- France: long haired and gracile
- Sweden: He should be older than your bro but I think he's the least different from him. Not sure though.

Give him glasses and he'd look like Sweden :)

have him wear glasses and he'll look like Sweden, but you could also get a fake ahoge somehow and he'll look like Romano xD at least a little bit..

Actually I was thinking Sweden too....
