Step one: Angle

Take photos of your doll from as low an angle as possible, their chest height or lower even. Put them up on a table or stool or something elevated if you have trouble physically getting low. Taking photos of them from a low angle will make the photos look more convincingly scaled and less "doll-like", as well as adding a more dynamic element. This one is easiest to bend or break, but make sure you're doing so intentionally. Be sure to experiment with different angles, even tilting your camera so your doll is at a diagonal in frame, for different vibes.

Bonus: incorporate foreground and background elements in your shot as well as midground (typically the doll). This will give your shot a lot more depth and help to ground it.

Step two: Posing

Arguably the most important step, nothing brings down an otherwise solid photo like a stiff and mannequin-like pose. First, take angle into account, pose your doll while checking the camera's view- most beginner doll photographers make the mistake of posing their doll leaning backwards and almost craning upwards, or even just perfectly straight, which ends up looking like theyre leaning back. Use those slouch joints if you have them, tilt their head down- further- further. Unless you have your doll looking at an airplane or something, you'll want them looking down at a lower angle, even if not looking at the camera. Just trust me on this one. Experiment and try for dynamic poses as well, humans don't often stand very square- twist the torso joint, put more weight on one of their legs than the other, angle their head slightly to the side, put one hand by their face and have the other relaxed at their side- think of how dynamic marble statues look, and the way the artists exaggerate weight distribution and asymmetry to do it. Try replicating that. Don't be disappointed if your doll can only balance standing square. Using a stand is hugely recommended when photographing dolls, you can edit it out later or just minimize it's appearance. A dynamic pose will draw more focus than the stand will. I've even used a tripod and some shoelace to make a very heavy doll strike some fantastic dynamic poses.

Bonus: think of asymmetry and dynamism when it comes to your dolls clothes too! Pay attention to the folds and flow of the fabric, little details make a lot of difference and can showcase the doll's character.

Step three: Lighting

My final suggestion is to play with lighting. Lighting can do an immense amount to impact the mood of a photo. Avoid harsh, direct light, like full sunlight, overhead lighting, and the like. Color can always be corrected in post processing- you don't necessarily have to avoid yellow lights, but having the right color off the bat will make things easier for later you. Aim for diffuse, soft lighting at first, like in a shady spot, on a cloudy day, or with a diffuser (a handkerchief or paper towel will do fine) on your light. Then start experimenting with different lighting types and colors- like rim light, or soft blue! You don't need professional equipment for this, most of my artificially lit photos are taken using a color changing fish tank light or a workshop ring light with some paper taped over it to diffuse it.

Bonus: MacGyver other things for your photos, not just lighting. Have a sheet of textured acetate? Make the doll look like a monet painting by shooting through it. Have a sheet? Excellent, you have a backdrop for portraits. An old mirror? Try making the doll kneel on it and interact with their reflection. I MacGyver almost every one of my doll photoshoots.

(All of these tips can be done with a cell phone, you definitely don't need a special camera. But, a camera can do a lot more things with depth of field and the like. If you do get a camera, I'd recommend a dslr with a decent auto focus, and a 30 or 50mm prime lens for it, with an f stop of 1.8 or so- it'll allow you to get really nice foreground and background blur in your photos.)
