Not bad for your first deer. I would suggest getting plenty of reference photos, and also go to
www.taxidermytrainingunlimited.com , pick up one of their really good DVD's. The only thing I notice right off from the picture is the ear location and hair pattern. Look at the location of the ear on the photo of the deer in your Avatar picture and compare it to your deer mount. Especially, where the top of the ear muscle meets the head. Good Luck!
