Not bad, but I feel a different type of 8-bit synth would work better for these notes. The lead around 45 seconds in is a bit loud. Overall nothing really stands out here, I feel the melody could be more active and vibrant if that makes sense. Not bad, but it's a bit calm and needs more to it, it's a bit repetitive. The lead synth sounds kind of off beat. Overall could use more, but not bad.
Please contact me if you would like to use this in a project. We can discuss the details.
