These are great! You have the descriptions perfectly. That is very close to how I envisioned them.

I like the way you caught that slightly haunted look in Argus' eyes.

Reya is stern and strict but also carries an air of compassion.

Sester is perfect. He's somehow got the sincerity but at the same time he has a mischievous and possibly devilish look in his eyes.

Wonderful renderings! I love them! Thank you so much vilakins!
