This is just next level shit
This is top quality.
Look at it! Firstly, it's the idea... What a badass thing. People repairing giant robots... Awesome.
Secondly, it's the composition! Look at it!
The way you've drawn each character, either getting on with the work, relaxing or staring off into space, you create a story right there! In just one image! You get a sense of how this is their life and what have you.
You really invite the viewer into their world.
The colouring is just amazing, a really gorgeous sky that gives off a surreal feel. I love how it actually colours the characters themselves, it's brilliant.
This piece is just amazing, can't get enough.
