Are you sure you’re willing to do several hours of work for only $5?
Your gig description needs to clearly describe the perks that are part of the package. (If a buyer is confused and there are other options, they’ll likely go to those other options, rather than take the time to puzzle out what you’re offering.) For example: What do you mean by “sound design & mixing” and “motion graphics”?
Always check your gig thumbnails from your profile. You probably only need one image of the program being used. Or, at least show you editing for other games.
There are several English errors in this gig and your profile. (Ex: In your profile is “instressed.” I assume you mean ‘interested’?)
“Languages: English - Fluent” is inaccurate. It should be ‘conversational.’ (I suspect that your spoken English is better, but this platform only permits text conversions, and yours isn’t quite at the ‘fluent’ level.)
