Looks good! You might be able to stack red brick around it just leaving an inch or so air space so the brick won't get too hot and pop, to dress it up in the yard. Might want to try a good hot fire and not stand too close, I don't know how hot a brick can get before it will pop. As a planter, the brick could be set right up tight. My welds look like a chicken pooped things together, and pecked a few holes for good measure.
