Update: I messaged the artist and politely told them that I was unhappy with the piece and pointed out each thing that was wrong as suggested by a commenter and explained that I would appreciate either a re-draw or a partial refund. They replied telling me that 'Well I am not use to drawing monster/partial human characters. However I will give you a partial refund.
I do request that next time you want a commission from me or any other artist though, to review their work and look to see if they are use to the image you are requesting to save yourself and the artist any undue stress.' and that I should have paid more attention during the stream. (My mistake as my internet was giving out) but they have agreed to pay be back half of what I paid within this week.
In my opinion not being used to a species doesn't excuse the anatomy but I digress.
Thank you so much everyone for the advice.
