Tadaa! Narvi and Vali! The first designs I’ve ever come up with that I didn’t want to immediately delete 5 minutes after drawing ‘em. 

Now, they are basically twins but for a couple things. First off, my headcanon is that Sigyn carried and had Narvi while Loki carried and had Vali. This led to a couple of differences- mostly with Vali. 
There was a lot of speculation that Vali could potentially be more Jotun-like (i.e. bigger, giant and blue, carried in-utero longer), however the opposite happened. Vali was born in less time than a “normal” Jotun pregnancy, and, while he was indeed born blue (as was Narvi) he was very small. It seems he, like Loki, is more a Jotun runt than proper giant stock. Both Narvi and Vali’s skin changes closer to that of their mother’s as they grow older, but Vali retains- faintly– his Jotun markings, while Narvi loses all traces. 

Even though they’re pretty much the same age Narvi has a tendency to act as the “older brother” and always keeps Vali near. They’re very close and naturally very curious, which is both a good and bad thing because they also inherit Loki’s nose for trouble
