I do actually take commissions sometimes! They're on a case by case basis and I take them as time allows.
Prices depend on several factors. Scale; the size of the piece in relation to how large that object would be in reality. Medium; there are cost differences in a piece made of polymer clay and one made in clear resin, or mixed media. Intensity; how detailed the piece is in relation to its scale - this includes things like paintwork complexity, texture, wings, hair, etc.
Please feel free to E-MAIL me with commission inquiries, I check dA about once a week so do not expect a fast reply if you note me. My E-mail address is Sovaeart@gmail.com
When you write please keep in mind the above factors when you describe the work you would like as they are what I use to price pieces.
