Nicely done! Not everyone has good sensibility when it comes to laying finish paint down with a brush. How one loads, and pallets the brush, and how they control the stroke are all key elements. Same can be said for the sequence of parts being coated, it takes a little methodical planning. The quality of the paint, and how it’s mixed too contribute to the end result, as does the environment that the job is being done in. Additionally as the saying goes, “it’s all in the prep!”
As a retired house painter who specialized in high end interior cabinetry and trim brush work, I know very well just how lovely, and smooth a coat of enamel, or even epoxy, can turn out. And it looks like you’ve certainly proven my point!
