Crocheting My Failures Into a Sweater Vest: A semi-informative vlog.

I made a mistake but that's okay because I'm turning it into a learning moment and I am crocheting myself a sweater vest using a pattern I made up even though I've never made up a pattern before. What can go wrong?
As promised in the video here is my "pattern"... disclaimer that I've never made an actual pattern and this is for my own size! Please feel free to use it as inspiration or a starting point for your own project. If you do, I would love to see it over on Instagram!
"Pattern"
Body: Chain 24 (or chain amount needed for torso width plus two)
Skip 2 chains, double crochet in remaining chains until end. Chain 2, turn.
Double crochet in all stitches across, chain 2, turn.
Repeat *-* until it's your torse length (from collar bone to however long you want it to be).
Neckline & Shoulder: Double crochet 4. Half double crochet 1. Single crochet. Chain 1, turn.
Skip chain and single crochet. Single crochet 1. Half double crochet 2. Double crochet 3. Chain 2, turn.
Double crochet 3. Chan 2, turn.
*Repeat *-* until strap goes from collar bone to top of shoulder.
Attach yarn to other side, repeat Neckline & Shoulder so each sides are mirrored.
Side Ribbing: Rib stitch along each sides of the panel (amazing tutorial here: mycrochetory.c... use the HOW TO ADD A CROCHET RIBBING AT THE END section)
Collar Ribbing: Rib stitch along the inside edge until you reach the short rows. For the next two ribs, instead of slip stitching into the next two gaps, skip one gap then slip stitch, skip one gap then slip stitch. Repeat once more then continue ribbing normally until you reach the other short rows. For the next two ribs, instead of slip stitching into the next two gaps, skip one gap then slip stitch, skip one gap then slip stitch. Continue ribbing normally to the end.
Make two of the above panels. Attach at the shoulder using a back loop whip stitch.
Ties: Chain 90, skip first chain, single crochet in all remaining chains until the end.
Make two ties. Pull through sides of ribbing at desired height.
