Can you improve my gigs?

[nurferaereen]

Hi I’m Ereen an illustrator,
New seller since June.
I have 5 gigs currently, 2 more in progress - doing more researches about them at the moment.
I checked my gigs a few times and realized how I didn’t include the additional options like colours and background, but I’ve fixed that.
Mistakes might go unnoticed if it’s only me who check it, so can you help me in improving my gigs?
Is it better to include FAQs and add more gig previews?
The gigs:
