Impressive, my good sir
Apparently your skillset includes being a dashing cavalry officer as well as Newgrounds' best artist...
I would jokingly guess that the one on the right is you, although the style of dress clearly indicates that the left is the original. Now, if you had switched the clothing... although genius knows no era, and is truly timeless. But as another reviewer said, a man with impressive facial hair (and those 'designer stubbles' one sees all too often these days don't count for a red cent) is often a man of great talent.
You really should consider selling prints of your works. They are definitely worth their weight in gold.
