i want to be able to do something besides chibis since chibis are so common around here and so far i havent sold any >_> so this is my first attempt and something more realistic. spent around 2-3 hours on it and would like to know what you'd spend on it/if it's something you'd buy. i also need to practice doing fullbodies..
Because the proportions are a little off, I'd probably pay around 6$ on it. I'm not sure what that would be in SP.... you could probably charge ~15 mil? The color work is amazing, especially with the shading you've got going on.
If I were you, I'd work up some more examples, work on the proportions of the eyes in relation to the brows, cheekbones, and nose (location is key) and then you'd be able to sell for probably around 15$.
Not a lot of people sell shaded busts, so you'll have a good market for that. If there's anything else I can help you with, don't hesitate to ask.
Who would pay real money $6 instead of 15m when 600 CSC can be sold for about 35m? The ratios need to balance out.
