I had a great idea for my first one, but when I took it to a tattoo guy and asked about it he said you can't really get shit done on your feet, or it will fuck up, so that messed up my idea.
Autobots are far better than the Decepticons. I never liked the Decepticons, even though they had Starscream and Megatron (Megatron was the most irresponsible toy EVER - when he was in gun form he looked at first glance like a very good replica... still very cool, though ).
Yeah, there are parts that turn out alright, but apparently you lose heaps of skin around the bottom of your feet, so if you get anything put on there it will fade really quick when the skin sheds. This is what the dude told me anyway, and showed me some photos of what it might turn out like.
