Looking for some guidance

Hi folks!

My item got a soft rejection while submitting it to themeforest, the reviewer told me that there are some inconsistency with the white/negative space.

This is my first time submitting a sketch design into this platform, so I’m glad I didn’t get a hard reject. However I think I need some fresh eyes to help me polish my design.

I’m looking for an experienced designer who can spend an hour or two with me reviewing my work and giving me some feedback. Please reach out to me (https://themeforest.net/user/crysfel) with your hourly rate, and we can take it from there.
