A great start! I like the pose you were going for with the couple, very cute. Here's a red line of it with a drawover of the redline afterwards:


Oh! Also, it might help to study cloth and draping. Many times you do not need to draw ALL of the folds and creases because it can become muddled and busy. You can draw the most important ones, like folds under arm pits and where clothing bunches up around the waist or elsewhere. Again, studying clothing and how it falls on the human body will clarify which ones to draw and how.
