This is a LoRA for Linka from the VK stickers. It was trained on the Illustrious model but also works well with NoobAi.
It replicates the original style well and is reasonably flexible. However, I recommend using it with other style LoRAs to better achieve the look you want.
I haven't noticed any major downsides. The only minor issue is that the style is more "baked-in" than usual, which means it may take more effort to alter the original aesthetic.
