what did you use for the lineart? It's so cool!
Your colouring is absolutely superb! Really love the shading ^^
This is radical!
Both your artistic skill and style all show here and they both look pretty impressive to the eye.
Your traditional drawings look glorious. Love Their expressions, especially Serperior's. The colors/shading looks smooth and vibrant. Excellent work.
P.S. Just noticed you forgot to add Servine's nostril(s).
