Their faces are done so beautifully! I think you have a great idea of where your personal style is going. Michael's face is done especially well. Your body proportions are also very nice. What can be critiqued about this piece is the amount of cleaning up you did. It still looks sketchy, and not quite finished. The lineart is what gives this away, such as with Michelle's left shoulder (our right), and their hands. It just looks like you need to go back in with an eraser and smooth out the black lines. The folds in her dress are very well done, but perhaps next time you could try more variation in line thickness, because some of the folds seem too emphasized. The last thing I will note is that both of their poses seem a little awkward, particularly Michael's pose. His legs are close together, which would suggest that he's putting all of his weight on Michelle. He's a big guy, so I would give him a stronger pose. Other than those things (which are easily fixed), you have a really great handle on what you're doing, and I hope to see more from you.
