...Ok, this is weird, weird as in weird kind of freaking me out right now lol.
You see, I am recently make a sort of comic(?) but they all GIF. And I started at March 01 just like you, and I only have 2 episode just like you too and my 2nd comic is about cat too...
... Here is the link to my comic GIF... https://tapastic.com/episode/627960
I am doing all GIF because I animated them on Flash first though then I convert them and animated them again on Photoshop. But it's really time consuming which is why I was planning to make it into a panel but still GIF ...just like you...
...ugh, now it seems like I am the one copying you...

Edit : Ok, I don't mind any harm, I just shocked here since well, we both using GIF, we both started at same date [March 01], we both only have 2 episode so far [although I may not make any episode until next month, again it's hard to animated and then convert it into a GIF] and both the second episode is about CAT ROFL.
So yeah, ahem, sorry if my post seems to be weird? English isn't my first language and I just really surprised at this ...event 0.0
Second and hopefully last edit :
Ugh so I just realized I just rambling about myself and not answering any OP question. ._.
So, GIF on comic is totally ok, I mean I have see some comic here that is all GIF which is why I make them all GIF on first place. Mine is small btw, never exceed 1 MB.
