OK, you did ask… And I’m no designer… But… And this is just my “way” of doing things, not the right way…
I’m on a 13in laptop, and the content is edge to edge, which I always feel makes it look crammed in, so I’d restrict overall site width to 1000-1100 px. 1200 at a push.
I don’t think your fonts work. One is very old style, the other modern. I would keep the text font and change the header to something a bit bolder, less fussy and more modern.
The subscribe box needs to be far narrower, say 600-800px and at the bottom.
The three column text area needs breaking up, too much in one section. Split it into three centre aligned segments and place between the image sections, or reduce it to two columns and keep it at the top, but reduce the width of the individual text columns to about 400px (so 2x400) with a good size gutter between them.
The text is a bit wordy too.Take out the superfluous words and you’ll be surprised that it still works but takes up half the character count.
Lose the red border on the slide.
Increase the font size in the menu.
I’m guessing by now you’ve already added in the panel background colour? Grey? Change it to the same as the header colour, and change the panel sections slightly by change the opascity, 40%, 50%, etc. Start at the top and have each panel 10% darker than the one above.
Lose all the RW credits in the bottom. They’re pointless and will just confuse the visitors. I’m all for giving credit to devs, but not your website real estate.
Final comment, before you never talk to me again… Re-do your logo. Sorry, but it looks like that of a real estate agents to me! Go for something more modern feeling.
Sorry to sound so critical. Remember, I’m not a designer. My real job is fixing bikes!
