I would say add some dark grey to the claws of Growlithe.
The Duck looks fine, I remeber seeing a show with him,but thawassome time ago. Anyway back to the critiquing. I suppse that was one of the hero ducks(Duck Dogers I presume) So the sahidng works well considering as that is how it would be shaded in the show for those dramactic type sceens.
If I recall correctly, that is Yamcha lying on the ground right? I resume from Dragon Ball, I can't remember but I think that is what he looked like.
You have done a good job 9/10(because no one is perfect, even if thier stuf is amazing)
