You are right...it does seem dim...but therein lies the dilemma...I brighten it up, it doesn't have the neon look...just the painted plastic look. I keep it as is, doesn't pop off as much in the final piece but retains a very realistic look.
Ultimately it will be Henson's call to make. They receive the final colors this week and will decide between the first version we showed at SDCC and this one.
