I've always wanted to have portal lions guard my front door. And perhaps one day I will paint a pair in the entrance way. For now, I worked up a small drawing that is a blend of several reference photos.
Most of the portal lions I've seen, both in the museum and online, look like this.
Note the glamourous curls that comprise the mane. This fellow is beautiful, but doesn't seem particularly fierce to me.
Then we have this pair. They too have relinquished a curled mane in favour of overlapping plates. But more importantly, look at those snarls! These are fierce lions and no one is getting into the door on their watch. Presumably, unless you have a whole roast chicken...two whole roast chickens.
I combined the elements that most appealed to me to generate my own version of a portal lion. May there be more lions in the future.
