Which are correct: 1-He looked like not a bad fellow. 2-He seemed not a bad fellow. 3-He looked like a not bad fellow. 4-He seemed a not bad fellow. I don't use sentences such as these and go for the usual structure, ie. 'He didn't look like a bad fellow.' but I think these four sentences are not incorrect although 1 and 2 are probably more common. As usual, I am not sure, or else I wouldn't have asked.
