Vision This is really stunning ! The pose, the colors, the lightning, etc. The only thing that annoy me is the position of his back legs. To my eyes, it looks weird, but I don't really know how to explain it. Anyhow, the effects are really amazing; shinny eyes and background. It totally get us focused on Ganon. Good job !
Originality Even if this piece of art is awesome, this is not really original. Most of your art is characters from games or other places. It is your style of art and it's alright, I am not complaining, I'm just saying that I don't see any originality into this. I'll still give you 3 stars because it's probably not eveytime that we see this character in that way.
Technique The details on the fur are simple amazing. It give some realistic to this creature. The nose and the body are also awesomely detailed. The background is beautiful even if there's not a lot of things. There's even some details in the eyes, wich is really stunning.
Impact That big creature makes me shiver. You really did a good job at making it look mean and bad. The look in its eyes and his mouth wide open makes it even worse. Good job.
Overall, this is a stunning deviation and you did a really great job on it. Keep the good work.
