Could I get some feedback on a website I made?

Hi guys,

I made a printing marketplace site with a php.

I would love to hear some feedback on my website – what you like, what you hate and what could be improved.

My website address is http://www.yoctta.com

Thanks!

Wow, you made that with a 3D printer? Impressive!

jkjk, I like it. The design is minimalist, no "wall of text", very visual, color scheme is consistent.

Is it a WordPress template?

I think it looks good, is the concept to allow people to design a 3d object then others can buy it? What stops people posting free designs and trying to sell them etc.....

Why is it necessary to have 23 boxes with "Sell your design"
Should these show thumbnail pixs of designs?

Does YOCTTA mean anything? Is it even pronouncable?

Should have about menu button -- tell readers what site is all about, where, contacts.

Ah -- like thingaverse is free for users?

Sorry I am an old geezer -- perhaps this design is good for Millennials, not me.
