If looking for a portrait session then add if you want this at home, outside, specific location or not sure. If venue has not yet been decided, please try to give an idea of area?
Just an estimate if possible. If enquiring about a portrait then please let me know how many people you are looking to include.
Any other information you would like me to know. This could include any particular style or poses you are looking for. If enquiring about artwork then please give details of what you are looking for.
