First, congrats on the new property. As mentioned above, rushing in and making a bunch of changes can disrupt a good property and in some cases can take a long time to correct.
The improvement you could make right away would be to create screening along the road frontage and the NE & SE corners. On some of my earlier properties, I always started working on the interior of the property and over time, regretted that I did not focus on the boundaries. If you create good bedding in those fields, you will draw roadside visitors ... people glassing your fields, shiners at night, and those that like to shoot at deer out in the filed.
I would suggest 2 rows about 12 wide of pines or spruce. Pine are faster growers and you can space every 8' or so. I prefer spruce (Blue or Norwegian) at 10'-12' spacing as their branches stay low to the ground and will provide a very dense screen. The trees also add the benefit of overhead cover and roosting for pheasants & turkey.
As the pines will take some time to establish, you could always do a interior row of MG while the pines or spruce are establishing themselves.
I doubt you will regret adding screening and the deer will be far more comfortable bedding without all the roadside activity especially at night.
