Hi, I have a great deal of experience painting varied characters and I'm familiar with Japanese armour and weapons, more of my work can be seen on Deviant Art under the name seraph777.
We could look at pricing, my bid is higher as I can create high quality paintings and doing justice to the intricate armour would take a fair bit of work.
1. I would first ask for all details, references and your thoughts regarding the characters, also the size and resolution of each painting. The time estimate is to allow for feedback and revisions.
2. I would then produce roughs for each character and send them to you for feedback, therefore we can keep them consistent.
3. At this stage I can alter/tweak the roughs as much as is reasonable and then produce working colour versions, at this stage I would still be okay with major revisions.
4. I begin work on the characters and email frequent work in progress updates to you for feedback.
I would ask for milestone payments for the completion of each character, working out to a sixth or the total amount for each.
Regards
Steve
