Looks nice and tidy.
Just that the TX is exposed and may take an unexpected bruse when your carrying the box and perhaps ruin a day of flying.
Other then that it looks neat.
Looks like plastic is taking over.
If you have the luck I do the next size up box will be 4 times bigger then what you need.
It also looks like you did put some work into it.
I was really impressed with the number of people here still talking about tote boxes and showing what they have or built.
But the poll on the tote boxes was a flop.
Keep the pictures coming and share the ideas
