I agree -- it looks great! I really like the look of the loosely stacked bricks -- they work well with your brick edgings.
Make sure to put up secure stakes for the tomato and keep up with tying them up. Once the stems toughen, you will end up breaking them if you try to straighten, and if you have critters like rats, they will go after the fruits so you don't want them hanging down. You'll have better options for protective measures if the tomatoes are neatly staked.
Good luck and enjoy your garden! It's so nice to see that elsewhere in the world, people are still outside playing in the dirt.
