Nice rendering so far. I like the mix of sharp and soft edges, and the vibrant colours stand out.
The blue coat around the man's waist looks a little too high up. The woman's bracelet needs to be moved slightly up and right, then skewed to match the direction the knuckles are facing. You could bend the woman's bent arm more to make her pose less stationary, but you'll have to move the hand's placement to match the position. Good work so far.
