Thanks for the feedback, I did keep neutral expressions and poses as they are just test images mostly but I really appreciate your response! And it's ok to say something is bad or flat out sucks, I'm not really sensitive about anything like that if it helps me learn.
You are probably right about females so I feel silly now!
I'm even thinking long-term of just paying someone really good to kind of do post work on created images and even help here and there with images to speed things up. My other business besides writing is interior design so I feel a little better with framing pictures visually and my writing has been involved for screens (TV/movies) so another visual medium at least as well. Still, it's intimidating because while I can write incredibly fast - and so far at least reasonably well enough to make a good living - my art speed on the other hand is glacially slow! I'm kind of lucky for this possible project because one person is willing to fund me a decent chunk just to start it if they can create one character (one of those I displayed) but time is my biggest enemy and I am not sure I can ever be fast enough with limited time to finish something this difficult.
I am in the same boat like you in regards of time. As long as there are descent explanations agreed by both sides I dont see why your project cant start. Practise makes one better so even with the postwork you dont have to hurry things. I am also creating a game with a friend of mine and one of our agreements is that we wont haste things. I dont want to burnout on something that for starters do for fun plus I also have a job that eats most of my time. So whenever I want to "escape" from the everyday routine, I just sit down and create a scene or two.
on the other hand if your project aims for money, you can always hire a couple of people you vet first, to help you with the renders and the post work and you can work on the storyline, character ideas etc, as long as you can aford them ofcourse or are willing to spend ( or invest) on what will propably be a second job with all its perks and quirks.
If you look around in this forum you will see art that could be to your liking and I believe there is also a forum where you can "hire" artists to help you out.
