:D For how much this commission cost me already, I couldn't do it.
Although I would've added the Master from Actraiser first, then Robotrek's hero along with both Nagisa and Princess Tira (to balance out the male/female ratio again) ;)
However, I did also want to include the rest of Will's party - Lance, Lilly, Seth, Eric, and Neil - and Ark's friends - Meilin, Perel, Royd, and Lady Fyda - but that would've been seriously overkill. :P
