I have full rights over my artwork. Even if you are the commissioner, the art still belongs to me, so I have the right to submit the finished drawing in my gallery (DeviantArt) and other sites (if you are not ok with it you must pay an additional price in order to not submit the drawing publicly).
Don't edit my finished artwork and don't remove my signature without my permission.
You must credit me if you post my artwork.
Don't reproduce my artwork for commercial use without my permission, don't use it for print-selling, and don't claim credit for it.
I have the right to reject a commission if I don't think I can work with it.
Payments before I confirm your commission will be considered as a donation.
All commissions won't be started before the payment is done (the sketch, however, can be sent before).
You can only cancel a commission before the payment is done.
Commissioning me means you agree to the terms mentioned.
