Drawing Pan - And Otters in General

Download for a better view!

Obviously this was sort of inspired by the awesome entries I've received so far for the "Together Whichever Weather" contest. They're all so good (go look at them!)

[OC CONTEST] Together Whichever Weather!I'm hosting a BIG oc-contest! 8000 points+more than 20 art prizes to be given away - anyone can join!
Theme
The seasons are changing, and with it comes all sorts of friendly and ferocious weather, it can be beautiful or frightful, but always unpredictable. It's probably the most common basis for conversation globally - but that's because it affects our lives like nothing else. So that's the simple yet huge theme for this contest: Weather.
Which weather is completely and utterly up to you - it can be happy sunny beach-weather, put-on-your-boots-rainy-weather or a raging winter-blizzard. Or maybe some sort of weather phenomenon you find interesting, like the mysterious aurora borealis, fantabulous double-rainbows, golfball-size hail, devastating tornados, intense lightning-storms, whatever grabs your attention (and the judges')! Whatever you do, challenge yourself, have fun, be creative!
Rules
The rules are pretty straight forward

I hear some people say they haven't drawn otters before, and I feel sorry for them as I seriously haven't been very helpful to them, and really, otters can be a pain in the butt
The reference sheet I had for Pan is correct, but seemed lacking to me, so I made this chart-thing! It's sort of a ref sheet but also a tutorial/note sheet on drawing Pan and other otters. Tips, charts, examples, whatever I could think of. I hope it's helpful, if not just interesting! Otters are seriously so much fun to draw, they're just so squishy and floppy and heavy and fluffy and clumsy and d'awwwwwwwww


Here's the old ref sheet, which is still correct (with some extra personality info I left out of this chart), it's just not very good-looking:
