Google Picasa API XML deserialization - follow up

Im trying to write a class to deserialize the picasa album feed. It has been pretty good so far, got some help to get started (here) and I'm almost there. I have a problem with two fields right now.

The gphoto:bytesUsed and gphoto:numphotosremaining want deserialize. I can't find anything wrong with it. Thankfull for any suggestions.

Url to feed: https://picasaweb.google.com/data/feed/api/user/{username}
