hmmm... Not sure, both are strong but Sparx doesn't seem to be in this picture making Spyro vulnerable to damage. That is if Sparx is still used that way after "Enter the dragonfly" haven't played any after that.
You used the old designs for both of them? Lovely.
But sheep aren't magical creatures, I'm not sure why he would be protecting them, except I guess if it was a ranch population and spyro's "hunting" could lead to the discovery of dragons. c: </nitpick>
