Sophia's new shirt, and my first pattern

It's my first pattern! Sophia was given this cute little top that I just loved, so I decided to make a pattern from it. Patterns are trickier than I thought. The original shirt had short sleeves and was made of knit fabric. Since I DO NOT sew knit, I had to make a few alterations. I wanted her to be able to wear it through the winter over a long-sleeved shirt, so I decided to not make sleeve and make life a bit easier. I also added the key-hole opening in the back, which the original didn't have. I used the same little button that I used on these shoes. Not too bad overall. I think I have a little tweaking to do, but I still like the overall look. And I have to think of what to "name" the pattern. Any suggestions?
