Hi Furya,
1. Pleashop (www.pleashop.com) is a e-commerce website. And it's meaning, we talk about shopping. And that's shopping trolley come up as the image of Pleashop's logo.
Then, to look this logo more stand out and attractive, i tilt this logo, and add swoosh under the trolley.
Tilting logo also gives meaning "movement", which conveying direction and reliability of this online shopping service.
The swoosh under the trolley also convey smile image, with trolley's wheels as the eyes, and swoosh as the smile. As we know, Plea on Pleashop coming from the verb "please", which describe Pleashop's objective to please their customers. And that symbolize with smile.
Last, the logo's color combined, is actually inspired from Pleashop's website.
2. PSD files? Yes for sure.
But for information, LogoTournament only allow to send AI/EPS and JPEG only as Final Files. If you need other format, you can provide your email, then the winner designer could send the file that you request via email.
3. I suggest to talk about further discussions later after this contest complete. And I'll provide my personal contact/email after this contest complete.
Because, i'm sure giving personal email when the contest still going is against the LogoTournament's rule.
Best,
Kutchu
