I'd say you are doing awesomely well. And next season you'll learn from this season and do even better.
On the tomato plants I think you did just right. They will develop strong roots and grow like crazy. And they will straighten themselves up if need be.
A suggestion I have is too set up some sort of trellis system to grow the cucumbers and cantaloupe vertically. You can grow more plants that way and they really do well. Keeps the veggies off the ground and away from the bugs and animals.
Cattle panels work well but simple set up (that I use) is simply to order plastic netting. Comes with 5 or 6 inch grid holes. You want to be able o reach thru. Then I simply bought those green plastic coated U Channel fence posts for my supports. I like the 7 foot tall ones best but I also have 6 footers.
But really, your garden set up is great!!
