here is my finished jacks i want to thank anogair for the help witht h e textures for the jacks and natronX from blenderwars for the help with lighting http://img45.exs.cx/my.php?loc=img45&image=almsotcomplete.jpg
nice render 
Aren’t there usually 2 spikes on jacks, (ie not all the ends have balls on the end)?
ya two spikes!
also you should have used ao seeing as the jacks don’t look anchored enough with just shadows.
furthermore a higher res floor image and a good nor map for the ground would have made it much better but all around it is a nice render!
keep it up! 
thanks its my real frist model i was working on the shadows for a while thanks guys
