Curb appeal advice

Submitted to Community Café

Hey guys, this is a picture of our house, it isn't a horrible house but it is very plain. There is a nasty little cement pad with remnants of old carpet that was glued down and I'm not sure how to get the glue off of that either. It's a very small house and I'm afraid no one will want to buy it  Do you guys have any ideas on how to improve the curb appeal?
