ORIGINALS: Pricing is different for each piece created. It's completely dependent on size, supplies used, time and effort/skill level required.
Pricing for custom pieces also differs. Also dependent on size, supplies used, time and effort/sill level required. Just because a piece is custom does not necessarily mean that it will be more expensive than an original piece.
Because of a high volume of want from my "personal" photography and prints, I will also be also selling my photography. If contacted I can get custom sizes photos printed on photo paper, mate paper or foam board. Pricing will vary due to size and a flat rate of $15USD to $20USD will be added to printing costs. All will have to be discussed, mostly to make sure you get exactly what you want.
