layout looks great!
I agree though, more photos and they are a bit dark. look up monitor calibration on wikipedia, you'll find some ways to make sure you're adjusting your photos as best you can. I had a lot of challenges when I was trying to use natural light so I invested about $50 on materials for a photo tent and some small photo fluorescent bulbs ($10 each). I made a tent out of a sheet of translucent flexible cutting board material ($7) and packing tape and bought a couple of clamp lamps. best investment ever!
also, your snowmen are so cute. you don't need to tell people they're your practice ones if you're selling them. if the quality is there from the first try, doesn't matter if you were just messing around
