Help with lewis structures and resonance forms (CH3NCS)

[MG5]

I need to write the lewis dot structure along with the 3 resonance forms for CH3CNS. This is what I had but it was wrong. Not sure what to do. Thanks.

Resonance forms do not involve the movement of nuclei, so 2 and 3 are wrong. Actually, 3 is a different compound altogether. Perhaps consider pushing the lone pairs on the sulfur and nitrogen on structure 1
