Ochem question regarding IR spectroscopy

Can you please help identify any other important function groups for the attached IR spectrum for 2 methyl acetinilide

I've started but I'm not sure about the absorptions at 3029.63, 2990.86, 2922.69, 1914.08, and the ones in the 1500's. Also, are there any others that show up in the other areas that I need to identify?
