He was not aware of the print source material for those cartoons until his grandmother began buying him three-packs of comics from a grocery store.

Samnee was so in awe of holding professional board with the Marvel logo printed on it that he could not bring himself to draw on it, and in a 2013 interview, indicated that he still had it.

He drew the Oni Press graphic novel Capote in Kansas around 2004 or 2005, inking his own pencils because that book's budget did not provide for an inker.

[6] While he was still working at Borders, he signed a contract to do a graphic novel for Vertigo, though it would be months before the writer finished the script that Samnee could begin drawing.

Tomasi would later recommend Samnee to draw a couple of short stories he wrote for DC's 2009–2010 "Blackest Night" storyline.

[6] In 2010, Nate Cosby offered Samnee the art duties on the all-ages book Thor: The Mighty Avenger.

Though Samnee initially was apprehensive about not being the right fit for that character, after reading Roger Langridge's script, he accepted the job, which garnered him his first major notice from readers of the superhero genre,[6] and the 2011 Harvey Award for Most Promising New Talent, as well as nominations for Best Artist and Best New Series.

According to Samnee, this implement feels similar to a dipped brush, but does not require cleaning, and allows him the convenience to work wherever he wants.
