wow that's seriously good. so much detail and stuff.
I love all the light flecks and the lighting and shading is pretty awesome, especially on the hood and cape.
I personally wouldn't say the lighting is "vibrant", as I would expect more of a coloured light source, like yellow or something, whereas your piece seems a little low on contrast I think (maybe it's just my own definition of vibrant). I think maybe because all the colours are quite similar perhaps? Definitely a bright light, and the shading matches the light source well.
lovely background and the little glow around the characters too.
but really great overall, this must have taken ages to draw!!
