wow. that's great!
well, even if the subject of a dystopia is dis-heartening... it's a great drawing/pic!
i love the shine on the gasmask/reflexion on the light/viewer, and i love the reflexion the light does on the goggles, so that we can witness for ourselves the horrible enviroment the cleaner is in.great work.
do more.
ps. i think, if you want to experiment with inking, you should draw a NEW pic, cause inking a pencil drawing, could ruin the picture, so better try this with a NEW drawing. keep this as it is, it's epic.
but try making a similar work, on paper, and after penciling it, ink it. then, we might see the (wonderfull) results! (but, please.. don't ink this.) 5/5
