Thank you very much, it means a lot coming from you!
Funny thing that, even when I thought a lot about the design long ago, this drawing came up when I stopped caring that much and did it without any reference, just using my "mental image" of Pico...
... And probably that's why he's wearing some blue jeans instead of his regular khaki cargo pants... I feel so guilty! In my design, I color-coded the characters after the Ludo game pieces (Pico=green, Darnell=blue, Nene=yellow, ???=red)... I'll use that greenish gray next time for sure!

I'm considering to make the rest of the gang. It'd be a series of 4 pictures.
Thank you for your kind words!

Why not an M-16? I love how big it looked in his hands...
I chose the Glock-17 because I wanted to draw one long ago and I had some reference available at that moment (I was trying to beat the clock with this one.). It's also a really small gun, so it's very fitting for the tiny hands of a little boy.
Still, I hope to draw Pico with an M-16 one day...

Oh, thank you! Actually, working the way I'm trying now, "drawing" and "colouring" are, in fact, the same thing... I draw main, coloured shapes and build detail up from there... I suppose I needed a new method of work.
