You have an interesting way of gaining inspiration.
Imagine that. Cloud and Pikachu together. What a fun thought!
You did a pretty good job with the anatomy. Though I find the position of the head (face) a little too far away from the body. The muscle-age in this is neat.
I like how the sword is still in motion and you blur/smeared to make it so. I also fancy how you did Cloud's profile.
...And check out that Pikachu! Looks determined to kill. >xD
Hmm.. Maybe a background (ex: a forest or a balcony of a castle) would enhance the picture a bit more, neh?
Anyhows, great job! :D
