gonna be real with you this looks absolutely horrid and needs a lot of improvement

since the light source is the sun on the back (im assuming), you should’ve done rim lighting towards the direction of the sun on your characters (if you dont know what rim lighting is, look it up)

or just get rid of the sun in the back to make the light source ambiguous (lol)

shadows are all over the place and make no sense at all, as shadows should be behind the actual object, not in front (unless you’re doing rim lighting)

the transparency overlap on the gun and stickfigure makes this look like a rookie’s work, turn that into a movieclip and transparency + tint it to make it look like an actual solid shadow

don’t even get me started on the left side which i don’t even understand enough to make a proper critique of, don’t try doing that ever again until you finally grasp the basics

look up references when it comes to lighting and shading, or study how light just reflects on objects near you
references and studying how other people do lighting genuinely do help, and i’ve been studying it on my own for a while now
while i do understand you want to ask for help here, everyone just seems to ignore your posts (lol)
so congrats to you for getting me to be harsh as hell and going out, but that’s just how it can be sometimes especially outside the website, you gotta get used to it

have fun with what ur doing
great job on the “attempt” at lighting
not so much on the actual lighting though
