it's not bad for a first set. i would recommend remaking the head though, the face feels unproportioned. the feet are decent, just make the sandals longer, it looks like it covers the toes and nothing else. the right bicep is just a copy-paste from your left, you should remake that so it fits. the torso looks pretty good! hands arent the best, but for a first attempt they arent bad. hopefully this helps!
make the general outline in blender and then add greater detail and finish in another program. Arms and torso color don't match the rest of the body too.
