I need some opinions / advice

I'm considering on trying a story based on deadpool as a displaced in Equestria. I'm a horrible writer and honestly I'm still not sure where i want to go with this. I have an idea about what i wanna write but I'm not 100% there yet. I'm considering a simi-human type Equestria like where one of my Oc's came from. I'm just beating myself up being most displaced are either pony type or anthro sorts.. Id really like to stand out a bit with this other sort but I'm unsure if anyone would like the concept. If anything I'm going to default to a Pony type just because of few things and well this picture which I will be using as my cover at.

Let me know if anyone of you would like to see this come out, ill also need help with grammar to get this story going and honestly i have no idea how long this is going to be it could go for awhile if people ask for it, or it might just end up being a few chapters then end at that.
Any who... please leave a comment I really want to hear what you all think.

Thank you!
