Watch the Strategy 3: Think About Shape online guitar lesson by Jon Herington from Ear IQ: Soloing Strategies
So, this one seems like a good example of how you can use the shape or arc of a solo - the different registers of high and low on the guitar - to build an interesting design. But there are other things to notice here, too, like choosing the right sound and degree of attack, inventing and choosing stuff that reflects the character of the song, in this case, stuff that reflects a sense of humor and a sense of abandon.
I didn't notice this until I had finished the record, but I realized in hindsight that a big inspiration for this tune was one of my favorite pop guitar solos of all time, one by Carlos Santana on a Boz Scaggs song called "You Can Have Me Any Time". It's a big ballad, and not in the same rhythmic feel as my tune, but there's a way he plays on it which is so beautifully emotional - he's digging in and it's a great sound - and it's unmistakably him, of course, since he's such an original. He's up in the high register and just wailing - I've always loved that and I'm sure that some part of me was remembering that when I played this one.
