Edited

So these are my first art pieces to be this detailed, and I have no clue what pieces like this sell for. It's not that good, but it's still sort of nice. Can I get some help please? Thanks! If I haven't gifted you already I will after you post :D
(PS: I like gifts too :3)

1) How much do you think adoptable pairs of these would sell for together? (Combined packages of the baby first then the adult)
2) How much do you believe the adult copys to be worth alone?
3) Do you honestly think these would sell?
4) What do you think of them?
5) Is there any improvement you think I could make? (Please be kind when critiquing, I am a beginner at this kind of art)

Another PS: Someone mentioned I need to work on anatomy, such as head shape because they thought it was a deer. This is *NOT* a deer, purebred anyway, it's a hybrid of my already existing original species Equus Razorus. Thus the anatomy is different (and pretty wonky!) because of it's species. (Which I have named Cervidae Razorus, supprise to all who have been stalking my Equus threads :3)

Good Tips & Reminders For Me-
×Lines here & there, especially on the white
×Finish the stupid freaking grass DX
×Work on blending
×Fix the back left leg
