Wow I am jealous!!! You learned to crochet with 10 years - wow. I learned it rather late. As a child I was totally uninterested in everything crafty (sadly, because my mother was a great knitter and seamstress) And a poncho is an ambitious first project :-D
Thank you for the praise and yes, it’s my first knitted sweater. I finished it this summer, but it was a huge act…I am not so good in reading knitting patterns and I made it much too long. So, I watched some videos and cut the cuff of and knitted it again (everything with a heartrate of 240) I forgot if you have a ravelry account, if yes you can find the pattern here:

It is not so complicated, because the sweater is made from 4 rectangles. The patterns are only purl and knit stitches… but it is not crochet (means: I needed ages to finish and it was not so relaxing)
