Steven does accept commissions. The characters will be based on photos that you provide and input you may have. Please remember the end product will be a caricature, not a true to life sculpture. He does not sketch out the sculptures before creating them, so he will not provide sketches to you in advance.
When placing a commission, you’d pay half down, and the remainder upon completion. Depending on how many orders are on his list, there can be up to an 18 month wait for completion of your piece.
