v1:
v2:
Personally, I’d go with v1. They’re pretty decent.
Also, I would tweak the bolts on the first image. The background is fine, It could be improved.
I like v1 and the last one a lot. Having a dark background and then these lit up bolts really looks awesome!
These GFXs look VERY good! I like the style of them! Nice job on these!
