It looks like a lion ^^ Rawr!!! XD
It looks amazing! However, mind if I suggest something?
Thanks and NO YOU CANNOT!! Haha kidding, of course you can suggest something
I reckon a wider range of tones and highlights, since the armour is metal it should be pretty shiny. Also using more orange and reds for the darker yellow tones instead of making it look kind of grey. Hope it helps!
Using watercolors and pens are very nice and very neat, and the colors are beautiful.
