If you look at Felix, the red butterfly boy in my album- he's almost a complete dragon- just hard to see because he's all... white. XD
Dragons are generally characterized by thick-looking, white scales on their bodies. That's pretty much it, lol. Your boy's scales aren't white, or particularily thick looking, IMO. Don't take any offense in that, no offense was meant- but he just looks like a regular HMPK to me.
