YES! that's right! i actually tried replaying it, several times, just from that point near the lighthouse, thinking if i go other ways, i will have an alternative ending, where everything will be okay. how wrong was i? >:
well, first of all... you need to know how to shade, even basic skill of shading is good enough to make a pretty similar effect.
then, you also need to know where to apply the shade. the thing that i think makes my art appear smoother lookin' is the fact that i use unnaturally shaped shades. it's hard to explain actually... well, because my art is only semi realistic and semi anime (i just can't fucking get rid of these Japanese animation faces for some reason... but it comes with practice...) i can freestyle with shapes, lines and proportions. naturalistic art is too strict for me... so... everything appears more smoother but with an edge at the same time, because i don't follow the rules of anatomy or lighting. i choose my pencil lines... and where they go.
i don't know if that made much sense... but there. that's the only way i can describe it.
same thing to say, why does it look so digital? BECAUSE IT IS! i heavily Photoshop it in the end. :>
i got a gut feeling there will be another one coming out at some point. though the ending clearly states Bookers death, you kinda... don't actually see Anna disappear. it's like the ending for Inception. :>
I actually had a weird idea for a sequel, that I will dub "Worldshock" where one has to travel between the world's of bioshock infinite, bioshock and system shock to solve multi-dimensional puzzles. Just a brain-fart.
