A few things i can just recommend off the top. I see her cage is on the floor, Maybe try putting it on a table or a stand for her, they dont like to be low to the ground as they feel they need to get up to "escape" in a sense, i always approach my girl from under her and slowly so she sees me coming, if shes low like she is everyone is towering over her and it might be stressing her out, she will puff up like that. Seeing the black spots like that she just seems stressed, also maybe provide a bit more cover for her in your cage, seems sorta open and she might be getting to that mature level that she would feel safer if she had more greenery to hide behind. I see at the bottom you have sorta a water rock bowl, she will not drink from that. Will have to get a mister or a dripper. Id say you have a good start just slowly build, it wont be perfect overnight. Im no expert but just sharing what ive gone threw raising my female vieled. She is def not 1 year old. Id give her 5 months maybe 6. As she gets older you will have to supply a bigger cage and a laying bin for her, that cage you got seems like that starter kit from zoo med. A laying bin she needs will not fit in there. She does not look fertile, if she was about to lay she would display her receptive colors first. To me she looks slightly to young to worry about that yet. Below is what my girl looks like when they are receptive, light green her black spots will turn blueish and she will have yellow on her.
