Read and heed this man's advice. The clutch must be disengaged before you can freely spin the rear wheel. Finish your installation then try it.
Also it appears after enhancing your first photo that the master link clip is installed backwards. You'll want the open end facing the rear of the bike as it enters the engine drive sprocket. Just pop off the spring clip and put it on opposite of how you have it now. Your chain is a little loose too. 1/2 to 3/4" of slack is where it needs to be.
