I'd love to see any pieces you have that are more along the lines of that final water colour (in terms of not referring so heavily to the original reference)! You have a beautiful grasp of colour and I would love to see more of your work.
I have paid between $20 and $250 for both physically painted and digital pieces (printed onto canvas). For commissioned pieces, I've only dealt with artists I know personally or who have been highly recommended to me. I've had a variety of pieces commissioned, in many styles. None have been very complicated or large in size, hence the $250 max price to date. Someone with little experience in commissioning would not - in my experience - expect to charge minimum wage per hour : in my country, Australia, minimum wage is $17.70. 10 hours at $17.70 per hour = $177.00. Whilst that amount must of course include materials, time spent communicating, and actually completing the piece, the reality is that a beginning artist cannot charge that kind of a price without an incredible amount of luck.
One thing I look for when choosing an artist is how deep their portfolio is. I notice that your chosen pieces are currently mostly in the same style, which may hinder interest in commissioning you. For example, it's hard to assess your grasp of anatomy with the references provided. That's not a criticism, please don't misunderstand me, just an observation. I personally would expect to see a wider variety of sample work in an artist than you have in this thread so far.
Having never commissioned from an artist online, I would be very wary of sending my money off to someone I've never met. I would check feedback and other public communications thoroughly, and if in any doubt I would have to pass. Having "vetted" friend's online stores for them, I suggest you do the same with at least a couple of people you trust.
Hope this info from the perspective of a potential customer helps.
