How will your character to the above webcomic?

Pinky and Ace would be totally bewildered as to why you'd even be showing it to them in the first place. They'd consider it the work of a young child and just not be interested.

Many reactions would depend upon the context in which this is encountered.

Two of the characters in Tales of SIG have adolescent children so say one showed it to their mother saying,
“Mom, look at what my friend did.”
Now Aura us from a very advanced space faring civilization and a piece of art produced with ancient tools would be interesting.
“Very nice dear, using ancient media too.”
“I know how you like comics mom. I said I would let him know what you think.”
And so on in a typical exchange between parent and child.


Alternatively it could be one mother showing the other what her child got from a friend. Maybe surprised that Aura has an interest in comics and so on.

The whole thing is context.

There doesn't appear to be an above comic, but if you mean the below comic, they won't be able to see it. My characters can only see colours on the orange/grey end of the spectrum.
