What program do you use btw for art ?
(Not to be rude or anything at all I swear please don't take anything in the wrong way!!)
I ask what program you're using because most art programs you have layers.
And layers are very useful when it comes to coloring.
When using layers usually you create a new layer UNDER the outline layer and then color.
Only reason I ask about layers/programs is because some of these looks like a paint bucket tool was used directly on the outline layer.
Mainly on the Mystical Pups, Reindoe, and the Dragsea!
You can see white around the edges on the inside.
Also another thing I have noticed with your work that when you color something black...you use BLACK. Like the color of the outline black. So then it just kind of blends in..hard to see the outline. When doing black you want to make it a little lighter. Like the black Ophear! Its not too dark!
Thats just a little bit of critique to help you in future art!
So your shading comes off as cartoony/poppy! Which isn't bad honestly I do enjoy the Ophears!
There are a few spots in the black ophear tho that you can notice that shading needs to get cleaned up a bit - x
Also on this one it doesn't look like shading was added to the back fin. Like the bottom part. The light shading is there but no dark shading. It just looks flat.
I really like the flat shading on this one - x
Could use a bit of work yet but it doesn't look cartoony. And it could use some light shading as well! But its a nice flat shading!
Again cartoony/poppish is fine for shading if that's what you're going for!
I do suggest making the light shading a little darker...its so white. But making it darker could in turn make it look more flat shaded as well. Maybe not so cartoonish and poppy idk it'd have to be done to see the difference haha.
I think the Flaring is pretty good! Lines a bit too thick and the fire seems a little off in shading but otherwise pretty good!
So come to pricing.
I'm not very good at pricing art because it can be different for everyone. It all depends on how much a person would want to pay.
If you sold just lineart I'd say maybe like 5-10mil ?
Flat colored maybe 15-20mil ??
Shaded maybe 25-30mil ??
I hope this all made sense and helped you out ?? xD
Again none of it was meant to sound rude!!!
