I would recommend taking the Skills Test for English form your profile. Your skill is clearly above ‘basic.’ Conversational, maybe?
100% satisfaction guarantee is very risky. It tends to attract scammers as they can complain to customer service that they’re not satisfied.
For your gigs that offer packages: Your gig descriptions need to clearly differentiate what perks are part of which package. (If a buyer is confused, they’re more likely go elsewhere, rather than take the time to puzzle out what you’re offering.)
Always check your gig thumbnails from your profile. The text (size, font, color, style, location) needs to be readable. Several images have been cropped oddly. Shrunk images don’t always look as good as the full-sized. (These are usually the first thing people will see, and a poor first impression will drive people away.)
There’s a LOT of copy/paste between your gigs and not all of it works well for each gig. Also, excessive use of capslock is unprofessional.
There is some formatting issues with your gig descriptions that make it/them look unprofessional. Also be aware that the formatting you use for your profile description only shows properly in the gig, and not on your profile itself. (Long lists usually look the most messy.)
Your profile description should be about you. You can mention skills, but save the details for inside the gigs themselves.
If any of the points are unclear, feel free to quote them and I’ll try to elaborate.
