Improving Footmen vs Grunts

[Kwanz4]

I am endeavouring to improve Footmen vs Grunts (from clan FvGE) by adding a lot more items and recipes to encourage more hero use. I am not done with the Ranger's vest shop, and I intend to add at least 7 more shops. Please tell me how I could improve the map: such as how I can make the textures better, where I could put the shops, what I should add to the map, etc.

My map!
