My gig title needs modification. How to improve?

[s_platen]

Recently I created my second gig, the title: "I will model 3d props or objects for your game",

it says misleading / incoherent / bad grammar in title and don't know why

I am not sure what is wrong, could it be, that it is just to similar to other ones?
My first gig has the title "I will create 3d assets and props for your game or other project", maybe they are to similar?

Another reason could be, that I changed the title early before publishing, it was "I will model 3d props or buildings for your game", which is still in the url when editing.
