I like it, but then, I love the Urbanmech and Flashman and even the Fireball. Maybe I got an egg fetish? Everytime I redid the Jackal, I made it look "better" but I think departed way too much from the base. This looks better while staying true to the Lightning Egg.
Splendid work here! But may suggest that for future work, maybe use a lighter value for any secondary elements, in this case, the trees in the middleground? I feel that I may help the more important parts be more important.
