The configuration seems ok and I hope it fits your requirements. However, I would make rules stricter. An example, your rule for HTTP is very common. Basically it passes any TCP packet which has source or destination port equal to 80. If this rule is intended to allow you internet browsing I would make it to apply to OUTGOING packets (instead both directions) or/and specified local IP in the source address field (if it is fixed, if not then your ISP subnet). If you want to create the rule for WWW server at your side then you could set it to INCOMING and specify your server IP in the destination field (along with port 80).
