Do you understand what this service does?

Great concept. Love the product.

Here's my take on it:

The message of the service is clear. A user would prefer to have a headline that is about his / her next event or the value that slick events adds for them. Maybe you can use your current headline in a separate featured section and focus the first headline on the end-user not the product.

The pricing strategy is good. I would suggest to also add a 2 month option because that is somewhat a good time to start promoting an event. 6 months options is a bit too much. You might want to reconsider that.

If you are to use a vertically oriented image use in odd numbers with decreasing heights on each side. So 3 or 5 would be better. This would also help demonstrate the versatile event landing pages.

Use an image for each of the value addition points with a consistent layout. For example (Add extra questions to your registration forms) does not have a product picture. Similarly some are aligned center, some left. It does not flow level. Use a consistent layout (2 by 2) image on one side, text on other. And switch sides after each value to add some twist.

Add all the common features in all your cards. It's a standard practice. It would make even the free trial look more appealing.

Last but not the least, use more spacing between sections ( ~120 - 160px) is a good number.

Hope this resonates with you.
