I don't have many questions! Email me and ask questions!
Do you take requests?
For the mean time yes, I don't know about the school year (got Biology) but if you email me and ask nicely and tell me what your char looks like I'll see what I can do.
Can I use one of your drawings on my site
If you email me and tell me what drawing and your website address, yes. But you must credit me in drawing that picture and have a link to my site somewhere on your site.
