It's a wordpress site - can't expect much there.

But yeah - feels and looks a bit amateurish..

Few things of the top of my head that needs fixing:

1.) Favicon missing (the little icon in the tab bar)
2.) Green SSL Bar is missing - you can use Let's Encrypt for that.
3.) Loading time around 8s - waaay to long. (e.g. smartsteem.com takes less than a second)

The design is personal taste - some like it, some don't. Me personally? I don't like Wordpress sites and nearly all I've seen look and feel amateurish. Loading times are slow, design is often too generic (it's a template) and not specific enough.

But these are just my 2 cents as a Developer. My expectations are prob. way too high, but the devil is in the details.

I'm pretty sure that the loading times can be increased - even with Wordpress - by tweaking a few things (minifying images, scripts etc.) but this is super important!
