Bird fork symphony was quite well done. The woodwind you used was a great fit. I think to improve it, perhaps give it a softer attack and decay at times to make it feel more alive. Your use of triplets was also very nice. It really is just a matter of more advanced mixing to make the songs come to life more.
You also said that you used your own image to create the AI image but that is very likely still going to rub people the wrong way so I highly advise not using AI anywhere in your art going forwards. Just use the base image as it will have more character and charm than any AI image could, and people especially appreciate real art in this scene.
