Can someone check my skeletal structure drawing of z-3,4-dimethyl-3-heptene?

___

This is what I know .. since it ends with an ene, it indicates a double bond and it would be located on the 3rd carbon. Z isomer means the substituents will face same direction, right?. Methyl means one carbon and the di indicates two locations, which are the 3rd and 4th carbons. Hept indicates 7 carbon in the whole structure,... so here is my drawing...

I wasn't able to open the Draw option, so here is an attached picture. Please help. Does it look good? How can I fix if not.
