Nah, they aren't, but neither is your time and effort ;D How long have you been drawing so far? How long do you work on each piece? Your time is valuable, my friend. Do not forget that!
A lot of people that offer artwork here are not really experienced with art pricing as far as I can tell.
Personally, I sold fullcolored and lined chibis for nearly a million before ^^
Never worry about being too expensive so much that you underprice. You will know when you are! And you can adjust your prices then, in retrospect, with more information on hand to use. \ o /

They are all adorable. I love your sketchy style. Maybe just copy and paste it? I don't know why the url stuff isn't eorking. But this is the correct address, it worked when I copied and pasted it into a new tab.

Thanks Neyite! and I finally got it to pop up! such a cut kitty!

Millions!? Wow! Thanks for the into Shiraishi!

To be fair, I've also been drawing for over ten years already and regularily sell my artwork for USD/EUR :)
I'd shoot lower than me for now, but as you improve you have every right to raise your prices to reflect your increase in skill! :D Just experiment and see what draws people in! And always do your best to put as much effort in as possible. That is what will draw in customers and keep them hooked. ^_^

Coloring yours now, I'll try to make it as accurate as possible, but the design is very elaborate

Could you draw my battle party-- Magpie Blacke, Raid, and Roseiro? Could you do them altogether in one drawing?

In return I will water your plants twice (as needed) with my incredibly-messed-up-so-large supply of Enriched Water.

Sure! I should be able to give it to you before the end of the week!

okay, thanks! I helped your plants.

Tada! For the first ever Sylesti I've drawn I think it turned out pretty good! though I didn't realize how dark the colors actually were, woops

Thank you so much!
