Thank you so much, I went with the literal interpretation for sides and then created them like that 2 & 4 are my favorites too :D

The tutorial for 4 had snow and I just had to do that even though I don't think my icon is exact but I think it fits with the theme! I redid 11 because I didn't like the coloring lol! I wanted to try to follow the tutorial but I wanted to do it my way because it's all about interpretation and 20 - I just thought a geometric texture would fit for the book cover interpretation!

Thanks for your comment!
