Feedback museum branding

Hello reddit,

I'd like to ask for feedback. To update my portfolio I designed a branding for a fictive museum.

The name of the museum is 'Museum of Digital Art' and it's a museum where art, light, and technology come together in playful interactive installations that spark your senses and open up your imagination.

For the visual identity I use pixel shapes and modern, vibrant colors because they give a digital, futuristic vibe that fits the museum’s tech-driven, immersive experiences. Together they create a bold, playful look that feels fresh and innovative.

The idea is to make the visual identity in motion, but for now I started with the visual elements in an instagram post. Don't mind the 'logo' and don't mind the font. I put that on the posts so you feel like it's an instagram post. For now I want to ask you what you think of the colors and the visual element. The shape in the center it supposed to be the letter M. The plan is to also create posts with the letters D & A, because M D A is short for Museum of Digital Art.

What do you think? I made a few different versions and I'd like to hear from you which one you like the best and if you have other feedback.

Be honest with me so I can improve my graphic design skills <3

Thank you so much!
