You did a great job following the tutorial. This is how we all learn. Your results are not that bad, just noticed that your colors are not complementary enough. You didn't use the principle of balance, the image and the effect around it seem much larger than the other elements. It totally covered it. There is much more to learn about graphic design and upcoming lessons. All in all you have done beautifully and I applaud your efforts.

I wish you success 👍
