someone who wants to model or is it that they want to show off your art? Either way that's cool!
And that dinosaur. wow. it wasn't so long ago if I count the months, but it feels like years since I was that happy.
But oh prrriissmacolorss!
My favorite traditional coloring medium is that brand of colored pencils, so I definitely recommend them. Either they're such good quality that you love practicing with them and get better, or their quality lets you use more of your potential ability. Not sure, but I certainly got a lot better with them.
By the way. .an interesting effect with those colored pencils, is to pick the color of choice, then use the white pencil over that. If you like that effect, then cool. But if it's too white, you can use something plastic to scrap off about half of the white pencil's opacity.
