Let's kick off with the modest homepage of your website, look at it as the front display window in which your customers look through before entering your website properly (clicking through). Put yourself into the shoes of a first time visitor, better still if possible get someone else to visit the homepage of your website and provide you with some feedback.
If you can't get anyone to assist you, do it yourself. From a customer's stand point ask yourself few questions.
What's the first thing you notice immediately upon arriving to your homepage?
Can you immediately tell what the website is about?Is it relatively easy to navigate around the site and find your products within a few clicks?
Where can you make improvements?
If any of the above questions requires you to start acting upon, make sure you make it your first priority to take action and start making improvements. Don't wait till tomorrow or the next day, go do it now!
