You should take a look at the game X for the gameboy and X-scape for DSI-Ware, it shares some similarities with the original Star Fox.
It has 7 color instead of the game boy palette that has 4, is a quick fix. Otherwise, good job.

Yea someone on reddit linked me a video of it, forgot that it was a GB game. It's quite impressive!
