I'm a developer having a bash at designing a church site for a relative and was hoping to get some feedback on what i've done so far. I tend to like clean, minimal sites so that's kinda where i'm going with this too. I've taken a basic wordpress theme and added most of my own styles to it. I'm not entirely sure about how I've used the banner image, as it's a good image but I've had to crop it and cut off one of the church spires. I'm also thinking that the widget tabs are pretty plain looking so some work is probably needed there too. The search input isn't quite aligned correctly just yet, so I'm aware of that.
I also designed the logo, so any feedback on any part of it would be great at this stage! It's a bit light on content at the moment, so the site probably looks more sparse than it would with live content.
EDIT, following the excellent advice below, I've updated the image and am curious about whether or not the banner is now too prominent to be a constant throughout the rest of the site. Any other feedback on the banner would be great. The rest of the page I still need to update.
