Rayquaza Sketch

Lol yep, I've had this for a while but never finished or getting around to coloring or inking this, which I ought to get to by now but you all know me I'm lazy XP
I'm rather proud of it, but I must finish it completely for it is only just a preview of what the full version is actually so you all must wait ;3
But here's the thing, I don't know what to use to color it, water color pencil, water color brush, pastel colors, color pencils? What do you guys think? Also it's been a while since I used either of those so I'm extremely rusty on those O.O; but it'll be good practice if I do use them. A,so I found my old sketchbook from my college art class so imma use that XP
