If sales haven't taken off, it's not the end, in any case, you'll be proud to attach this work to your portfolio
. You've qualitatively for yourself and are not in a hurry to put the made design product aside. For example, it can be reused and developed in a fictional case. If you've made a mistake and drawn another Food Delivery UI kit, like many beginners, you can come up with and describe the process as if this work is done for the customer and how you approached it. Based on this story, you can write on Medium, and scatter cool graphics in Dribble and Instagram. You may get valuable feedback and new subscribers. You should always re-use your own graphics to improve your portfolio and create an audience.
