'The Secret Files of the Spy Dogs' (TSFotSD) is another one of those animated series that attempts to give an answer to the question of 'what do some pets do when their owners aren't around?'
...in the case of TSFotSD, the answer is 'saving the world'. :P
Ok there's nothing original here, but I've seen a pawful of episodes and can safely say I've seen worse! XD
I know that doesn't tell the reader anything, so... I guess it's best to show rather than tell.
TSFotSD has an 'X-Files' vibe to it, despite its silliness. :p
Anyway, my card shows Mitzy (left) and Ralph (right), the series's main protagonists. I just kinda started drawing and came up with this---I had both looking up at something (or someone) they don't like. Seems Mitzy has some kind of device on her wrist, and Ralph's holding some sort of controller or radio.
I'm not privy to the spy dogs' activities, so your guess is as good as mine. ^^
Anyway, we might have a clue in the form of this 'Invader' pencil from Dixon (perhaps something from space is attacking?). Either way, the Invader is an easy choice for delineating ACO cards---it's drag is smooth, and despite the darkness of its lines, they will erase if needed (just don't overdo it).
Most Dixon pencils are good. :3
I have an Invader of an earlier vintage, but I seem to've misplaced it. :P This one's a bit more recent, but is still plenty old (either vintage is worth saving if you happen on one).
