- So first off, definitely don't rush the whole shop thing - take your time! You've got as much time as you want to make more examples - I'd say make some more, figure out how fast you are with these and what breed/s you enjoy drawing the most.
- As far as starting points go, 750g for these coloured sketch headshots feels about right to me? There's some loose lines going on, it's not entirely clean. I think you could - and should - consider charging more for annoying genes you might have some trouble handling, like Flaunt or similar.
- Honestly, it might be an idea to just not offer apparel right away? It's a bold move, but your strength seems to be with rendering different dragon breeds/genes and actually making them look different. Why cover that up with apparel? (And besides, ancients can't wear apparel in the first place, and I think your veils would sell, so.)
- Critique-wise - would I be right in saying that the one on the bottom is the most recent? Regardless, it's the style I like the most of the three. It's to do with the lines - they're definitely softer, but they also feel a bit more present than on the other examples. I'd encourage you to look at whatever you did to get the third example, and do more of it, haha.
- I think you could be a bit bolder with your shading and highlights? Like yeah, rendering white is kind of a pain, but even on the third example, Diaphonous is a pretty sparkly gene. Maybe have a play around with some shadows and highlights on a seperate layer, and see what happens? Try adding extra shadows in places like where the mane is going behind the head on the third example, and play around with highlights that aren't necessarily white. Why
not bright red, or purple (reflected light off the black neck)?
- Everyone's facing left and looking horizontal! I get they're headshots and there's a limited number of ways to pose them, buuuuut headshots at different angles can really open up different moods, even if it's dragon-facing-left-but-looking-way down. Dragon necks can also convey a lot - here's
an example with some different neck poses that help add to different moods. (To me, the S-neck one looks more regal, the arched/hunched neck one looks more quietly intimidating, and the one on the top right has a lot of neck shoving into the frame to give it more force/momentum.)
- Also on the pose thing: have you considered cheating? Or- okay, not cheating, but there's lots of headshots out there of birds, lizards, and snakes that make decent reference material when trying to draw dragons from the dreaded front angle. You can break them down into shapes, and then exaggerate whatever shape you need to.
