For anyone interested. I've added an extra stage to my drawing process. Here's how it all goes -
Various sketches. Final pencils, and then inks.....Here's where I've changed my process. I used to ink (on watercolour paper) then scan and add colour and tones on the computer. I convert the linework layer to multiply and colour underneath, adding tones on a separate layer. As I try to maintain a fairly organic look I decided to do more of the tonal work by hand with coloured ink. I think it worked out quite well, even though I still did additional toning on the computer. Hopefully as I practice I'll get better at the hand toning and maybe try more washes to eliminate as much computer toning as possible, making for a more streamlined process for me, something which I've been working towards. The other handy thing about hand tones is I plan to do some masking (solid colour shapes without outlines) and that should make it easier.
And here's that final piece again, if you compare the two, you might notice I wasn't happy with the head, and shrank it down slightly - I try not to do too much altering on the computer, but sometimes you just have to! I might do a few more superhero pics, as I've had an idea for another.
