I did the piece in washes of gouache, followed up with details added in pen and ink. I then scanned it up and made a couple tweaks with photoshop (very few, tbh since I suck at PS). The monsters are my take on the aquatic species of skale that are common in the Guild Wars world.
And last week's challenge was a guardian sylvari. Sylvari are plant people and the guardian is a type of fighting class in Guild Wars. I just couldn't not draw it.
