Cheers for the comments guys! I've still got lots to do going forward. I am focusing most of my time on the map so there is at least a solid foundation to work with and then I will move onto sorting out the rest of the playable units. I am also making the map and playable units as true to scale as I can. I know we're probably used to seeing a person model bigger than the actual vehicle or building and I know some may say whats the point in bothering with it, but for me it makes the vehicles stand out and try's to replicate their size but on a smaller scale.
My next work on the map will be to create a reservoir in a lower corner of the map. There are no large bodies of water near to Riverdale so I plan to base the reservoir off Jerome Park Reservoir nearby. I am hoping in the future this will enable the way for water related operations.
As always please give me feedback on the images I post with the map as I want to try and make it a mix of rural and urban upper New York City. I will leave you with a screenshot showing the changes with a previous image I posted.
