Here is one more vehicle I worked on for Turtles.  The Stealth bike with the shell in place.  The drawing is missing the mechanisms that move the shell pieces into place.   Model built in Sketchup and finished in Photoshop.

Finally some putting up some new work on my blog.  This is the turn for the Shellraiser on TMNT.  Design was based on Byron Penaranda's concept.  This shows the Shellraiser in the lowered position and the rear Manhole cover gun in the open position.
