Please always post the URL of your feed as well as the Store page when you have a question. For references, yours is at
Feedburner is not involved. Your feed is not properly structures as a podcast feed for iTunes, although it does have an 'enclosure' tag and so the episode appears there (in fact the tag is duplicated, which is harmless and will be ignored, but it would be better for it not to be).
You feed, which is constructed in WordPress, does not have the required 'itunes declaration' in the second line:
<rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0">
and is lacking any 'itunes:...' tags (though without the 'declaration' they would not be read anyway). As there is no 'itunes:image' tag your image will not appear in the Store.
I can't advise on how you should go about correcting this in WordPress. It may be possible to find a setting to do this; or there is a plug-in called PodPress which is designed to make podcasts in WordPress, and which you might like to investigate.
