I love how your quilt turned out & really like the fabric you selected. Your friend is going to love getting it from you. Don't you worry about the mistakes....everyone has a whole lot in their first quilts but as time goes by & you learn more you will find that you are making less mistakes. I have to suggest that you never point out your mistakes to anyone. If you are gifting quilts, the one who receives it will never notice them & will be so happy to get something from you that you made with love. Also, after a quilt is washed a lot of those mistakes will never, never be noticed.
Thanks for sharing pictures of your first quilt. It's a real beauty & your on your way to a great, rewarding hobby.
