Just wanted to share some pics of my upgraded Optimus Prime Kreon. For this upgrade I used the basic upgrade set found here
, and the torso expansion set found here
(for the feet). Using the torso parts for feet gives OP a bit of height over Blue Streak.
I used paint markers to color the parts and found that the WSF material would really suck it up. The paint actually bled through the material giving me a nice uniform coloring. But if you don't want solid colored parts I recommend sealing them first with a clear coat or I've heard some use Future Floor Polish to give the material a smoother texture.
Thanks for checking him out
