i totally agree. I have seen a pattern about the kind of content WT is looking to feature. While they value unique stories and overall craftsmanship, they mostly seem more interested in webcomics that update consistently (namely, update every single week with little to no breaks)
They look for consistency and commitment above all.
This was only on the platform for about 5 months but updates like crazy! Over 5 uploads a month. It has a unique premise, a simple art direction and a moderate success and reader engagement (~16k subs. ~70 comments per upload, and over 1200 likes per upload) i also remember it was frequently featured on the front page too.
And they got a featured offer in the span of only 5 months, give or take.
This made me really motivated, and i feel for your next move you can try staying on schedule and have an upload ready every single week if you aim to be featured. Break your long uploads apart if you must.
that being said, i see you already hit the 1k sub mark, so congrats! and best of luck : >
