Earlier this year, we introduced the heartwarming and impressive series of illustrations by Tokyo-based French anime artist Thomas Romain (Symphogear, Space Dandy, Aria, Macross Delta, and Basquash!). Called the Father and Sons Illustration series, Romain takes sketches of characters designed by his two sons and gives them an amazing anime style facelift. Romain is making good on his promise to one day put together the collaborative effort into a picture book for his sons by continuing the series with several new drawings.

While Romain's art is as great as always, it seems that his sons' have leveled up their artwork and detail, perhaps inspired by their dad's efforts. They've started including design instructions and labels, which no doubt help the pro-illustrator, who says he started the series when he saw how much fun his kids were having sketching them, and is happy to get back to hand-drawn quality time after working so much with digital illustrations. Take a look at these awesome new drawings, which include golems, snakes, and fire warriors!
