Hi there I was hoping to get a review on my boost converter design, the converter is boosting the voltage from a 3s battery (nominal 11.1V) to 19V.

I would really appreciate any advice I can get, I first created my own buck converter where I chose all the parts myself, the design ended up being very large and I have a space limitation on my PCB, so for my second design I got help from TI WEBENCH, which is a tool that chooses the components for your regulator based off the parameters you enter. The tool gives a schematic and a pcb layout, although for me the layout provided was a little hard to follow and seemed quite large, I decided to do my layout based off the datasheet recommended layout and was hoping to see what is thought about that. I've provided images of my schematic and layout, an image of the TI WEBENCH recommended layout, and regulator datasheet and their recommended layout.

I know that this is a lot to look at, even just a glance at the layout I've provided to see if there is anything obvious sticking out would be greatly appreciated. Although my main question is why the TI WEBENCH layout uses such larger pours than the datasheet layout. I assume it is due to heat dissipation, and am wondering if my layout will be fine using the datasheet layout.
