Here is an oldie, but still a good one. I made this back in the days of R.I.D. Transformers. I posted this on Transformers custom boards back in the day as well, but I wanted to share some better pictures of Ironhide.

This one done in my pre-dremel days, so everything was hand sanded which was a pain. It started out as a RID X-Brawn I sculpted the chest with Squadron White Putty. And restyled the alt mode into a Ford Escape. The head is from a RID Wedge with some minor mods. I also smoothed over the right fist, and made a two removable fist for his right arm to make his arms looks a little more in proportion with each other.
