Hi all wwb:ers

Just published my new website made by the great Wysiwyg Web Builder 12, thanks Pablo and team. Have done it with breakpoints down to 480 pxl for now, don't know if I shall go down to 320 in the same site... or create a standallone mobile site, that redirects from the main site?
Which is the best option you think??
Did this new site because I changed my business name from Mega Store to Chévere. I did a redirect from my old url:
www.mega-store.se that has a little intro. Direct url to the new site:
www.chevere.ec
Any suggestions and opinions appreciated.
