Don't worry - traditional's not gonna die any time soon. xD The only reason we see it so much here is that we're on a digital medium. Digital looks good here, while traditional pieces look good in person.
But. Pretty nice, bro. Pretty nice.
Oh. A tip on the shading. You've certainly got having a definite light source down, but your shading looks a little flat because there's only one light source. This is rarely the case in real life, and using either multiple light sources or at least showing reflections of light from a subject's surroundings can really make things pop.
The reflections thing is my personal shading love, really. xD
It's like in those egg-shading tutorials you find all over the Internet. They usually put a lot of stress on reflected light. [link]
Also, never use black for shadows in a colored piece. o_o It makes things look much more lively to use adjacent hues, like if you were drawing something green and tinted the shadows blue. Apparently it also works with making the light cool and the shadows warm, but I can't really explain that since I haven't figured it out yet. xD
Brown shadows also work. Just something that's not just black or a base color with black added in. ;o
