I won't parrot the "Sniper no sniping" crowd because I genuinely don't care, but I will say when there is a series with an active group working on it, you should bare minimum aim for a similar level of quality and contact the group before you post anything. Especially on a website like MangaDex where as you can see people are pretty tribal about these matters, it can come off as unexpected and rude to see a new group post a new chapter for an active series, which is heinously stupid but that's the hand you're dealt around here.
That said, your upload is rough in a lot of ways, low image quality, inconsistent typesetting, poor editing, etc etc. I'm not opposed to seeing multiple groups work on a series independently, all I care about is overall quality, if anything I think it's great to have a new group trying to advertise for talent and build up experience, but this was a pretty weak showing in general and all I can say is aim higher if you do actually continue to work on this series.
