Hi Kiki! It's nice to meet you.
I'm interested in this position, please see my portfolio here: layerto.carrd.co
For a rough estimate of rates, I can make sprites in the $40-60 range (depending on complexity) in the style you see at the bottom of my site. CGs can vary, but I'm more than happy to discuss further.
Feel free to send an email to layerto@hotmail.com anytime. Looking forward to hearing from you!
