Hi David; it is the Lion Roar/Great Wall kit? It looks nice!
Maybe you should take a look at some molding lines that needs some scraping (the brake/clutch bar and the "maneuvering bar"? -sorry, my english is not good)
I recommend you try the figure painting with acrilics, either Vallejo, Andrea or artistic ones. If you need some tutorials, take a look here:
