model generating bad random images

[M Nithish]

I trained my diffusion model in tensorflow based on this implementation and and after training for 450 epochs(on landscape dataset) ,my loss was around 0.015 (mse) and I generated a few samples and generated ones were very bad or random. Below are the generated images for 1000 time steps .

I just want to know is this a training issue , does my model need more training to further reduce the loss (currently : 0.015) OR is the problem in sampling technique.Can anyone help me please?
