I saw yours there this morning ( its nice by the way ) but it was only for a short time before more came through
I am assuming the file is NOT zipped at all? In which case on your MAC you can either “compress it” and upload that zip via dashboard BUT make sure the folder you have is just the theme NOT containing the help, PSD etc.
Alternatively again make sure it is JUST the theme folder and upload it via ftp (WP contents >> themes >> drop the folder UNZIPPED here)
Design fundamentals like spacing as alignment need improving. It needs way more festures and a more refined style. Psd files need to be expansive and offer a lot to a very very high design quality
The concept is col but you have a lot of validation bugs and the level of design is off. Typography is plain, contact page has too much space below the form etc., footer and header needs work,
Maybe if you code it but the detail, attnetion to detail, alignment and level of features etc. are not right for PSD
If you don’t assign a featured image it should not show up? Then just add it within the post as a media element?
