Let us know what you think of our site.

I think this looks pretty good.

My 2 thoughts:
1st - on the footer, is it supposed to say "Copy brothers 2014"? Is 'copy' supposed to be for copyright?

2nd - just a thought, but maybe have the menu only collapsed where you need to click/touch it to reveal when you are on a smaller screen size & tablet, but be fully visible on bigger screens. Here's an example: Auth0

But, either way, I still like it. :-)

It's a solid start. Let me provide you with my feedback.

From a UX point of view I wouldn't hide the menu items on a large screen. I think you will have less interaction with these menu items, and you have plenty of screen space to have them. You could A/B test it, but I think the navigation will perform better when it's not hidden behind the hamburger menu on larger screens.

I'm not a super huge fan of the city skyline pictures. They seem very generic and blah. They also don't show off what you do, and this large hero unit might be the most important visual to welcome new visitors. It just doesn't make the connection for me who you are or what you do. Show off your work, not someone else's.

I would also move up the description that explains what you do above the fold. I have decent sized monitors, (1680x1050) and I have to scroll down to see We are Bro, a creative agency specialising in a variety of skills that we use to improve your business.

Also, I feel the tag line might be too generic. Looking at your services list it looks like you guys basically help develop branding for businesses through the use of print and web services. So maybe a tweak like a creative agency specializing in unique and essential branding development used to improve your business. That just came to mind right away, but immediately I understand you are a branding or marketing agency (still generic but in a good way) and that your designs are unique (anybody can find the same clipart logos everyone else uses).

And your services page looks unfinished. Being a creative agency, people may expect more. I assume this page is unfinished. It feel that way compared to the rest of the site. That's easy enough to work with though. I think at some point added examples and interactions with content here will certainly help put the polish on it.

I give you all of this because I really think you have something here. Please take this a positive constructive criticism. It's well meaning. It's the best criticism I can give to make you guys be better. So go get it!
