Excellent use of shading, awesome job on the white webs to outline the costumes, and love the use of blue and red for coloring. Eyes are amazingly done! I wonder what the eyes would have looked like pure white!
Also enjoy the fact you have used him upside down.
The hands are brilliantly done with form, size, and dimensions/proportions wonderfully done.
You could have built up the neck/trap muscles a little bit more, but the effect is good nonetheless.
Also enjoy contouring webs on the suit!
All in all, a brilliant work of art. I look forward to seeing what else you come up with in the future.
I HIGHLY recommend you redoing this photo with symbiote spider-man or even the iron spider-suit.
