Hi,
I'm looking for some feedback on my site. Like many "developers", my design skills aren't as strong as I'd like, so I thought I'd ask the experts (that's you!). It's a statistics site with charts and tables drawn from doing some log analysis.
It will be used by corporate users; both technical and non-technical alike.

I've come up with a couple of different styles so far (the "light" is my preferred one):

Light Theme

 

Dark Theme

There's no mobile version (maybe one day... if I ever get a mobile device to test it on).

Any feedback welcome, but especially colour, layout, style, structure.
Thanks!

I'm not a designer either, but I prefer the lighter one, I'm not keen on the box shadows on the dark one.

 

You are probably aware but you must must have a mobile version. I have recently changed to designing mobile-first. 50% of your visitors will use a mobile.

 

If you are using Chrome, use the inspect element tool (right click) and then use the option for toggle device mode - then you'll see how it displays on a variety of mobiles, etc.

Thanks for the feedback James, appreciated. The light one does seem to be the preferred one from others I've asked too.

 

A mobile version may appear one day, but as this is for the corporate environ I've made it low priority (Firefox also has a mobile-toggle in its dev-toolbox).

 

Does anyone have any suggestions for potential improvements to the lighter one?
