Hello,
I'm a versatile and flexible illustrator/Animator, with some years of experience in a studio, and also as freelancer. My strongest value as illustrator is my capacity to be flexible on my style, you mentioned several projects so I think my versatility might be useful for that goal. Please, take a look on my portfolio to check my wide range of styles.
I'm also quick, although I don't know what's the amount of work required I can invest, at least 30 hours a week if necessary. Even more if the project requires haste. Also, the prize might lower depending on the amount of work to do.
The way I usually work is I do a draft sketch, and I show it to the client. If they want changes I apply them, and once everything sketched is approved I move forward to line art and color, at this point checking again with client for changes.
Always keeping the client updated, of course. I do not charge extra for the changes.
Please, take a look on my portfolio/blog so you can see my wide range of styles and techniques so you can decide if I can adapt to what you need or not.
I do have experience working in Illustrator, Photoshop and even 3D if required at some point.
If you have any question, don't hesitate to contact me. Thank you and have a lovely day :)
