the gun itself is pretty good, but doesnt realy fit pb2s style
im doing a quick 5 min trace over it and showing to u in a more pb2ed style
first of all, shaded paiting looks good but doesnt really fit most of pb2s artstyle, use it only some times, also use bigger outlines and if youre doing details like grids and stuff, make them bigger
i pb2fied you gun in like 10 minutes just so you can see it with bigger outlines
but thats a really great start, when i started i also made small outlines so thats not really that bad, just try to make them a little bit bigger and it will look really great!
