Pomegranate

I'm really into the aesthetics of the psychedelic 60s, and I've managed to make this, but I'm still a beginner with paint.net. How can I smoothen the bumpiness of the top and bottom parts of the text?

Thanks for the help and welcoming, but I managed to pull it off using Grid Warp! Select the shape you want the text to morph into with magic wand, and then invert the selection and use grid warp with a high amount of columns, using the invert selection line as a guide for each dot.

I'm trying to morph my text within a circle, kind of like with this image, but I'm trying to keep the characters going straight up and down.how can I do this with paint.net?
