Well, this is probably my most accomplished custom yet, in terms of matching a particular style. My old Casey was alright, but it's a couple of years old now and I knew I could do better. He was pretty simple to put together - I used a LCBH Savage Dragon legs & lower torso, TNA figure upper torso & head, SOTA Vega arms and Mattel WWE hands. Hollowed out the TNA torso and sanded down the Dragon figure's lower torso until it fit in the upper section. Had to make new wrist joints as I shortened the Vega arms by about 1/2". Also slightly resculpted the left bicep, abs and waistband. The head was a full sculpt on the TNA head, leaving just the ears.
The golf bag was from a Simpsons Freddy Quimby figure, with a couple of zips and straps added. The bats and golf clubs are (I think) from a Movie Casey Jones, the hockey stick was styrene sheet with vinyl tape.
Casey fits in pretty well with the turtles - He's listed at 6'2" with the turtles coming in at 5'3". April's way too small to look right with him, though. She seems to be in a true 6" scale whereas the turtles (and Casey, by extension) are in more of a 6.5" scale.
