Alien Siblings

I started working on these characters just... two weeks ago I think. This drawing is one week old so I'll probably change their design a lot of time.
I already started doing a 3 pages comic and... I like it? I'm not used to work on my stuff mostly because I'm scared it will turn into shit. But with this I'm feeling different, even if it won't be something famous I'll add this to my history as an artist and I'll enjoy working on this!

Anyway, brother and sister aliens from a Original Story with racers, illegal stuff, guns and weird animals, called "Supernovae Racers".
