Yay you made it for the prompt!

Ahh what a neat idea! Certainly would be cool to see more development from all 3 of these characters! Looks like they're all flying towards a sunset!
It's amazing what you got done it the short time available! Even with some of the more evident points that Sovereign has mentioned it still looks great! While Etta's expression looks good, both Pterano and Petrie's are spot on!
Glad to see you stop by and post this artwork!

(and remember to give me a shout if you ever need physics help!
