Its abit hard to make out Maluxia from the Stock, maybe bring him out a little bit more? Otherwise, i like it :)
Yeah, try to highlight Marluxia's face a tad more to make him more noticable. Otherwise, it's nice work!
the third one is the best out of the three and like they said make him alittle more noticalbe but other then that i like it ^_^
The last one is the best just doing more lighting for Marluxia face like they said and it should be fine really. :)
