I open 2 slots for references! (Human and furry is ok)
If you want to take a slot, write under the first comment.

1) back + front + head = 170$
2) back + front + half = 180$
2) back + front = 150$
3) front + head = 100$

+ head (Each = 10$) (for example, show emotions or profile)
+ details (Each = 10$) (for example, details of appearance, clothes) (Chibi in clothes = 15$)

Examples of prices:

back + front + head = 170$

back + front + half = 180$

http://www.furaffinity.net/view/22654154/
front + head = 100$ + head 10$ + 2 details (eyes and clothes) 20$ = 140$

Everything is discussed individually.
For example, a separate image of the eyes, mouth and spout can be counted for 1 detail.
NSWF details are possible.
If you want to insert some text into the reference, check it, I'll insert it without correcting the probable errors.

Payment via Paypal (full prepayment).
