Well even though I took these pics with my iPhone I think they are worth sharing.
I started off going the "digitalskull" way which was easy until the part where you have to hook the green gem up to the hulk arm in a way where it would still fit Superions Energon socket. without a whole lot of cutting which I didn't see in the tutorial I decided against going that route as I didn't think I could cut it good enough to look good.
Round two. Started it again using the second tutorial. Not as hard as it looked and now Superion looks great. I'm going to talk to a local customizer to paint the arms for me but even the blue looks way better than the pictures lead me to believe.
