Welcome to the challenges, Matt!
Thank you so much for sharing your work with us. I think you have some really great things going on with your projects.
If I were to make any suggestions, they would be to:
1. Lighten the background graphic. The sky graphic is a really nice touch but it weakens the contrast between the airplanes and the background. I made a super subtle tweak to fade it out a little.
2. Scale the planes up a bit so they use up more of the screen. Since we're talking about comparisons, I think the plane elements should be a larger focal point.
Overall this is really solid work. Hope to see you around the challenges.
I updated the recap post to include your work:
