I sort of agree with redape your feet look fine to me as in pointed slightly outward or forward or whatever. I don't think you should force your feet to point forward because that puts alot of stress on your body. My old instructor was always telling me to point my toes straight forward and when I got off my knees and ankels killed to the point I could hardly walk and I was only like 10. Other instructors we have had haven't really cared. You should point your toes where it is comfortable to you I don't mean they should be facing completely outward, but find a place inbetween perpendicular and parallel to the horse that feels comfortable to you.
