Looks pretty good.. The cork board on the wall maybe could use some more work.. the bump on it is repaeting a little too obviously and the color seems a bit too saturated... too red I think.
The drill and other tools on the table look a little floaty.. the shadow needs to be darker where the tool would be be touching the surface it lays on..
The green spill seems draws my attention and leaves me wondering what it is suppoed to be from.. maybe a jar with some green goo spilling out of it would be appropriate..
The drill bit looks too yellow and does not look like it is made of metal..
The screwdriver shafts also don;t really look like metal and their handles aren;t registering as plactic to me.. they need more gloass and a well defined reflective highlight on them..
The texturing ont he tool box is very nice .. I like the rust looks great...
The modelling on the drill is great and the sahder looks pretty good.
