College student starting a dog treat business. Feeling discouraged.

I’m an Animal Science student and since I’ve learned quite a bit about animal nutrition I’ve decided to start selling homemade healthy dog treats and simple cakes with 100% dog safe ingredients and ingredients that benefit their health. Ive been doing it for my own dogs for quite a while so I thought why not try to sell some. I do well with the baking and creating the treats but I cannot decorate for the life of me. It looks terrible. I’ve done some cakes and the customer loved them, but now I’m doing some holiday themed treats and I hate the way they look. I’m starting to feel discouraged because I’ve seen some posts from other dog bakers and they look AMAZING. Im not very artistic in that way and even with practice I’m not sure I’ll be able to create that. This might be dumb but I was so excited and now that excitement is dwindling.
