So right away I think the thing that is going to be the biggest thing between you and a featured pick is art. Your comic seems to be a post-apocalyptic story that features robots instead of humans, which is IMO very unique and if we're looking at premise alone you have a very strong case because it'll bring in an usual audience that is probably older men/women. However, likewise, this plot is hard to engage in because the art style is a little too close to a saturday morning cartoon.
In general, I think making the art more serious would go a long way. Though I don't think the art is bad at all, there is a lot of room for improvement, that I think you (or whoever your artist is, since you said we?) should be pursuing. This includes more dynamic angles, thinner lines, more varied line weight, wider shots, etc
Like something like this shot, that I personally find excellent simply from a compositional standpoint (using a hole in the ceiling to show your main character both illustrates the setting to give us an idea where your character is located, the loneliness, and the wear and tear of the facility they are located in) it could be improved a lot artistically. Consider using stock assets if you have something flat and patterned like a tiled floor, and using cement textures. I also really think you should boost up the shading by like 99 degrees, and maybe try to add some atmosphere.
Your story relies heavily on this feeling of isolation and a sort of melancholy sadness and apprehension of constant war. You need to make the viewer FEEL this through dynamic art, which means pushing the shading a LOOOT more.
Also, more wide shots! A lot of your shots are very small, and crop some part of the characters or setting off. Give us plenty of large, wide shots so we can see this factory the character is in and get a good idea what the main characters look like, completely.
In terms of story, I find it immediately interesting and the concept is very good. You will have your work cut out for you since all your characters are robots and that is harder for people to relate to, but I think pushing the dynamics of the art like I mentioned previously will be able to breach the gap between the reader not being able to relate to a metal machine by showing the feelings the machine may be experiencing through the setting, and thus having the viewer empathize through the feeling of loneliness. I personally find a lot of intrigue in stories like this, but yeah, if we're looking at it from a potential featured perspective the art needs to improve as well.
Good luck!
