I'll start off introducing myself:
I'm 16 and genderfluid (any pronouns). I'm autistic as well as being diagnosed with ADHD. I mention this as it does mean I'm not exactly 'normal'. I'm low needs and am generally able to understand those around me but I do have trouble expressing myself in ways that others understand.
I've realized that because of my mental health problems I am not at all built for a 'normal job.' Art and writing is a passion of mine and I want to be able to make it to a point were I can rely on income from it. So I'm starting out now!

I don't expect any pay for projects that I'll be on for a week or less.  Past that I would want some type of payment, doesn't have to be currency though. Gifting software, or heavy exposure, and such could also work. 

Currently the only examples I have are these pixel sprites as I have a habit of deleting personal work to free up files and never think to save them.

I can also do concept art. Currently I'm not offering up non pixel asset services for personal reasons, but I can do non pixel concept art.
In terms of writing I'm rather versatile. Despite being autistic and not being able to express myself I've always been able to fit into other characters even if their completely different, setting myself in their shoes. I can write plot lines and lore, even side filler things like books and random emails if you have a game in need of those.

If you're interested please contact me at: ktalamorgan@gmail.com with your project and what work I'd be doing!
If I really like your project and you decide you'd like to keep me around longer than a week then I might just keep working for free as well, experience and accomplishment means a lot more to me than materialthings.
