Well you can do what you like - I'm wont give you a lecture so take the information with a grain of salt.
A couple of things to think about:
- Check where you are getting these statistics. When you search 'female' and set 'sort by highest price' look at the quality of the models, many of these are about $250 and then go down from here and your quality is higher than this.
- Check multiple platforms for average prices, just because you sell here doesn't mean that's the value of the product - consider your options (some range up to $600 and that is worth it for a high quality rigged female model).
- Professionals in the industry are not worried about high prices (within reason). They are looking for quality content and happy to pay the price for it as long as its not crazy. ($150-$200 would be a bargain price for this item)
- Generally higher prices indicate higher quality. Prices that are well below the standard are usually warning signs: something has been rushed, its not what it seems, it could be stolen - things professionals will consider before purchasing as they don't want to be painted into a copyright corner.
- What value does it bring the customer, so if I value my time at $30 an hour and that model takes me 40 hours the model has a value of $1200, buying it for $150 just saved me $1050 of my time. Lots of people don't have the skills for this type of work so if its in demand it has a high value. It could also take someone else 3x longer to make this model so the value is scaled from this point of view.
- Profit: Think in a business sense, if you sold 15x $25 model that's $375, if you sold a $150 model 5x then that's $750 (minus commission). 5x Great reviews is gold in comparison to 15 customers who say nothing.
- Over time as quality content increases globally at this point is a good time to lower your prices as your content may not be in as much demand.
- Like a mosquito biting you in the night, small things have accumulative consequences. By offering high quality content at low prices you affect the entire market by bringing down the cost of all items in that category - you are in the race to the bottom. The flip side is by offering value to your customers you can join the race to the top. For example: its PBR, its real-time ready, it can be used in multiple render engines etc, these items add value to your content and give you a wider audience thus demand a higher price.
Again this is all things to think about, you can keep your prices the same and test our your strategy any way you like, I'm not biased either way. I'm also in the race to the top so what you do has little effect on my marketing strategy which is to provide value to customers. You can buy the shoe from the brand store or you can buy it from the knock-off shop, you get what you pay for and you earn what you are worth.
