I have recently been updating my comic art portfolio so thought I would post some examples of my work. These included samples of my full colour illustrations as well as some pencil only versions (all artwork by me only).
I just posted something in the 'seeking talent' thread. 12-20 pages and a cover (20 written/paneled/storyboarded, possibly edit down to 12 and have finalized character concepts for the dual main characters like the ones you posted above) Check it out and message me if you are interested! I need good art to bring the character concepts to life and I'm willing to pay for it.
Someone that can do pencils and color would simplify things a lot. I can send you the first few pages if you are interested and want a better idea of the tone/setting, etc.
