Looks like a good start! My only criticism is - it looks like you might not have pressed your garments. To get a more professional look, it's important to press each seam as you complete it, and then carefully press the entire garment when it's finished. Kind of a pain but it really does make a difference to the finished effect. To press curved seams such as over the bust, you need what's called a "tailor's ham," which you can buy or make. http://www.burdastyle.com/techniques/how-to-make-a-tailor-s-ham
Pressing the seams as you go is probably even more important than some of the sewing! It also sets the thread and blends in any minor crooked stitching...a good iron is as important as your sewing machine...great beginners tip here!
Funny, when you sew have sewn for a long time, these things are so engrained that one tends to forget these important tips for the newbies that are taking up sewing!
