Outdoors with a bright but clouded sky you get nice natural soft light, which should give you nice pictures.
In these shots I used the following items:
LIGHTS: I have the Elinchrom D-lite RX 4 studio lights, as well as the portable (still pretty heavy to take with you, but it's more 'portable' as in 'has a battery pack') Elinchrom ELB500 TTL Dual To Go set. I use them with 2 softboxes 60x60cm (big enough for statues). I use one as a main light and the second as a fill light to light the back and give some contouring (shoulder, shield...). Softboxes give you a soft light without hard shadows, but still give you the chance to play with light/shadows (as I like most in my model photography too:

CAMERA: I have a Nikon D800 and a D810, because I do a lot of dance photography. This is moving subjects in a pretty dark environment, so a bit of a challenge sometimes. I think for the statues, with the controlled light and static subject, any DSLR would do the job. The lens is more important. In this case I wouldn't see much difference between my €3200 D810 and the €500 D5200. It's in challenging situations the D810 takes the advantage.
LENS: I have a portrait 105mm lens, but I don't use it for the statues. The reason is these have a relatively long focus distance. I use a 105mm macro lens from Sigma (105mm f/2.8 macro). These are used for insects too. It's important it is a real 'Macro' lens to get close on the subject and to be able to focus at close range. The one I got was pretty cheap, since I got it 2nd hand. The good thing with macro lenses is even the cheaper ones are pretty good quality. One thing you might have to check: not all macro lenses have an internal focus motor. The one I got hasn't, so unless your body has a focus motor it won't autofocus, and you'll have to focus manually. I don't know how this is with other camera brands, but Nikon only has a focus motor in the higher end DSLRs. Most native Nikon lenses have the focus engine in the lens. Third party lenses (as Tamron/Sigma) often don't, which often reflects in the lower pricing.
