For my part, his drawings, I find them ugly, and recopy. Even his personal creations, I find them not that beautiful.
His designs absolutely do not reflect the series. When you compare his creations (copy) and the old ones, the old ones had much more charm!
Any attempt on Reverse Image Search only ended up with nothing resembling a source. But have baby Serenity anyways. If anyone has better luck or knows the artist, please, let me know.
