Patriotic indeed but somehow... the lion doesn't seem like the most ferocious lion you could've chosen for the conveyance. XD In a way I suppose he looks almost human, with a mane that almost seems to resemblance some historical figure as well...
The arrangement's nice, educational with both country borders, flag and 'coat of arms'.
But such a comical clash between the grim expression and the little flag. XD
Nice work! Gives a good impression of Bulgaria, a little ferocity but a little humor too.
